Which trait is controlled by a dominant allele and which is controlled by the recessive allele?

Which Trait Is Controlled By A Dominant Allele And Which Is Controlled By The Recessive Allele?

Answers

Answer 1

Answer:

Purple Flowers

Explanation:

It is because purple flowers are the dominant over the white flowers so it will end up as purple

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. A parakeet that is heterozygous for blue feathers (dominant) is crossed with a parakeet that is homozygous for white feathers (recessive).

A parakeet with white feathers. A parakeet with blue feathers.

According to the Punnett square for this cross, what percentage of offspring is predicted to have blue feathers?
25 percent
50 percent
75 percent
100 percent

Answers

Answer: 50% of the offspring are predicted to have blue feathers.

Explanation:

Simple Dominance

I'm going to assume since the problem didn't say otherwise that we're working with simple dominance. This is usually the first kind of inheritance that we learn about in school.

For every gene, there are two alleles, a dominant allele (B), and a recessive allele (b). We represent these as a capital letter and a lower case letter. For this problem, let's use a 'B' for blue. There are three combinations that these can come in:

BB - homozygous dominantBb - heterozygousbb - homozygous recessive

If the alleles are the same, we say the organism is homozygous for the gene. If it has one of each, then the organism is heterozygous.

In simple dominance, if there's a dominant allele present (B), the organism will always show the dominant phenotype (in this case, blue feathers). So, the only offspring that can have white feathers are the ones with a bb genotype.

Punnett Square

A punnet square is a tool used by biologists to determine the probability of two organisms' offspring having certain genotypes. For this simple cross, where we have one gene with two alleles, we just need a 2x2 square. On either side of the square, we're going to put the two alleles of each parent. Then, we'll take each allele on top and add it to the boxes beneath it. Finally, take the alleles on the side and place them in the boxes to their right. I'll attach the completed square to my answer.

Interpreting the Results

Once the entire square is filled in, we'll see the following results:

Bb x2bb x2

2/4 offspring will have a heterozygous genotype (Bb) and therefore have blue feathers.

2/4 offspring will have a homozygous recessive genotype (bb) and have white feathers.

So, one-half, or 50%, of the parakeets' offspring will have blue feathers.

50%

A geneticist is studying a disease trying to determine how its inherited. DNA testing was completed on three generations of a family and a pedigree chart below was created based on the results fell in shape means that the person has the disease a Hatfield shape mean that the person carries the gene for the disease but does not have the disease males are often affected then females females tend to be carriers what term is the type of inheritance is this

Answers

Answer:

X-linked recessive inheritance

Explanation:

Since the disease is primarily present in males vs females, it is a s.ex linked disease.

In X-linked recessive inheritance, males tend to get disease b/c they only have one x (the other is y) which means if they get the bad "x" copy from mom then they definetely will get the disease.

Females can be carriers b/c they are XX. If they get a good copy from mom and suppose a bad copy from dad, they can still be healthy b/c the good copy is dominant. They will be carriers (cuz they have the bad copy) but themselves wont have the disease.

2. Compare hormonal and nervous control of homeostasis

3. Classify the mechanisms through which hormones affect target cells, the major chemical classifications of hormones, and the principles of positive and negative feedback

Answers

In this question we are going to answer a series of questions about the human endocrine system, hormone release and homeostasis.

What is human endocrine system, hormone release and homeostasis?

1. Endocrine glands produce hormones and release them directly into the bloodstream.

Hormones are the products of secretion from the endocrine glands. They control various activities in the human body, hence the importance of these glands.

2. It is through the feedback mechanism that, for example, the regulation of hormone secretion and the control of temperature and blood pressure occur.

Thanks to this control, it is possible to guarantee the harmony of the systems and, consequently, the homeostasis (balance of the internal environment).

3. Hormones can be divided into four groups, based on their chemical structure,form of synthesis and storage, solubility, half-life, form of transport, receptors on cell and mechanism of action:

PeptidesSteroidsAmines and Eicosanoids.

Both positive and negative feedback are extremely important for our body to function properly. However, these two mechanisms have differences. In negative feedback, the body produces a response that reduces the initial stimulus, while in positive feedback, the response reinforces the stimulus.

Marsupials are found in North America and Australia, but they would not have been able to swim across the ocean. According to scientists, how did this group of organisms come to live on two separate continents

Answers

Marsupials come to live on two separate continents when both continents were attached to each other.

What is the reason for the presence of Marsupials?

Marsupials are the group of organisms that come to live on two separate continents a long time ago when both continents i.e. North America and Australia were joined or attached to each other. The supercontinent named Pangea began to break apart about 200 million years ago which results in the formation of continents.

Before this is broken, the Marsupials move to the Australian part from the North American part so we can conclude that Marsupials come to live on two separate continents when both the continents were attached to each other.

A table showing the observations in an experiment investigating how plants respond to gravity. The top row shows observations from a plant grown upright in a pot. The observations are as follows: the stem grew straight upward on day one, straight upward on day two, straight upward on day three, straight upward on day four, and straight upward on day five. The bottom row shows observations from the plant grown in a pot on its side. The observations are as follows: the stem grew straight outward on day one, it started to bend on day two, more bent on day three, bent like the letter L on day four, and continued to grow in a bent fashion on day five. Gravity does not affect the growth of a plant. Gravity has no effect on the plant grown on its side. The stem of a plant will grow downward with gravity.

The Case for MarsBy Alexander FisherA mission to Mars should be the next step for NASA. There are many reasons why going to Mars is important. First, Mars is the most likely planet for us to colonize. No matter how expensive, we need to work on getting there as soon as possible. Furthermore, the technology that we would need to develop to send humans to Mars would directly benefit our economy here on Earth. Just look at the money-making products that have already resulted from NASAs space efforts: invisible braces, water filters, cordless vacuums, to name just a few.Although we have already sent robots to Mars, robots cant take the place of humans when it comes to studying the planet. A robot may break down. Also, it takes robots much longer to cover the same amount of ground than it would a human. Think how much faster we could learn about the planet if we sent humans to work alongside the robots! Finally, claims that there will be significant health problems for people who travel to Mars are wrong. Studies have shown that radiation levels on Mars are not lethal to humans. Sure, we would have to live in a dome at first, but over time, we could use science to change the atmosphere and make it possible to go outside, just like on Earth! The choice is clear. We need to go to Mars now!Article 2MarsA Waste of Time and MoneyBy Juniper SpringsWhile it might be fun to imagine traveling to Mars one day, now is not the time to go. For one thing, it is too dangerous. The atmosphere of the planet is more carbon dioxide than oxygen, and its very cold. While there are claims that the radiation levels on the planet are not lethal to humans, that does not mean they arent dangerous. We dont yet know what the long-term health effects will be. As of now, we do not have a solution for this problem. It is foolish to think a dome would be able to protect us from all of the radiation.It would also be impossible to build one large enough to house as many people as would want to go. Also, going to Mars will be expensive. Why spend money traveling to a planet that is so dangerous and far away? That money could be better spent addressing problems here on Earth.Furthermore, it is unwise to think any inventions that come about as a result of our race to Mars would make up for the cost of getting there. We are already able to send robots to Mars. It wont be long until our technology is so advanced that a robot will be able to do the same tasks as a human. It is not necessary to go to Mars right now.Part 1 Graphic OrganizerFill out the Compare and Contrast Chart based on the two articles in this worksheet.
