Dark fur color appears to be an adaptation for mice living in dark environments, as both the frequency of the characteristic and the allele that generates it have altered. These findings further back with the theory that selection is context-dependent, as dark mice were preferred in some contexts but not in others.

<h3>What is mutation?</h3>

A mutation is defined as a change in the sequence of genetic letters, called bases, within a molecule of DNA.

In a population, more offspring are born than can survive, resulting in competition among people. Individuals that possess a certain trait are more likely to live and/or produce more offspring than those who do not possess that trait. The context in which a species exists influences its selection. Characteristics that are advantageous in one setting may be detrimental in another.

New mutations cause black color.

Fur color is controlled by many genes (4:29).
Most genes are identical, but dark and light rock
pocket mice differ in one gene (Mc1r; 4:55).

Explanation:

First let's define a few things.

An allele is a variant form of a gene, each gene can have two or more possible alleles, one inherited from each parent. The copies, however, are not necessarily the same. When the copies of a gene differ from each other, they are known as alleles. A given gene may have multiple different alleles, though only two alleles are present at the gene’s locus in any individual. Alleles can sometimes result in different phenotypes (observable traits), with certain alleles being dominant. (overriding the traits of other alleles)

Let's make a table of our bird's alleles.

We can see from the phenotype of her bird's offspring, yellow is dominant over white, and patterned is dominant over solid.

Let's use Y for dominant yellow, w for recessive white, P for dominant pattern, and s for recessive solid. I know dominant and recessive traits usualy use the same letter with recessive traits being lower case, but in this case it makes it easier to determine phenotype.

Our parent birds are dihybrid cross which involves 2 genes coding two traits, with dominant yellow pattern both represented by PPssYYww.

So look at the chart. It has then been color coded by the traits the bird will exhibit. We have:

9 birds with Patterned Yellow Wings

3 birds with Solid Yellow Wings

3 birds with Patterned White Wings

1 bird with Solid White Wings

This is the same ratio Maria found in the phenotypes of her birds.

Now we can answer the questions:

Number of genes and alleles? We can see that there are 2 genes, one gene for pattern, and one gene for color, but there are also 2 alleles the variant of the Pattern and the variant of the color.

Which phenotypes are coded for by the same gene?

<em>yellow and white; patterned feathers and solid - </em>This one as you can see from the phenotype chart, and as discussed earlier, there are 2 genes, one for color, the other for pattern.

yellow and patterned feathers; white and solid
