In Hardy-Weinberg equilibrium, the sum of the dominant allele frequency (p) and the recessive allele frequency (q) is equal to 1.

The question says that 49% of the population consists of mice with the homozygous dominant gene, therefore, the dominant genotype frequency is equal to 0.49.

The question asks us to find the frequency of the recessive allele (q). In order to find the frequency of the recessive allele, we must first find the frequency of the dominant allele (p). According to the Hardy-Weinberg principle, the square root of the homozygous genotype frequency is equal to the allele frequency.

The dominant allele frequency is 0.7. Using this, we can solve for the recessive allele frequency.

The r-selection strategy for reproduction is typically seen in environments that are very volatile and unpredicatable. It has a variety of characteristics including high brood sizes with a high mortality rate, and fast maturation with very little parental assistance. Low brood sizes are typically seen in the k-selection strategy for reproduction.

The best choice is that the individual has a mutation that accounts for his/her green eyes. This mutation would yield a new phenotype that was not a result of direct inheritance from the parent generation.

Codominance cannot only occur in one individual offspring; rather it would occur in some form in all offspring with respect to the given trait. Independent assortment always occurs in cases of typical Mendelian genetics.

The alleles for gene A assort independently from the alleles of gene B, meaning that the genotype for one does not affect the genotype of the other. Even though there are two genes, we can solve this problem by answering the question separately for the two genes.

There are three possible genotypes with respect to the A gene (AA, Aa, aa) and three possible genotypes with respect to the B gene (BB, Bb, bb). Since genes A and B assort independently, the possible offspring will be the product of the possibilities for each separate gene.

Listed out, these genotypes are: AABB, AABb, AaBB, AAbb, AaBb, aaBB, Aabb, aaBb, aabb.

Using a punnett square one can see we get 1/2 with genotype Tt and half with genotype tt.

Allelic variation is a mutation in the SAME gene causing different diseases. Genetic heterogeneity is when different mutations can lead to the same disease. Variable expressivity is the varying degrees of disease with the same gene mutated. Penetrance refers to the percentage of people with a mutation that develop a disorder.

Since colorblindness is a sex-linked gene, female children need to have the sex-linked gene from both their mother and father in order to be colorblind. In this case, the mother will donate a colorblinded gene to half of all offspring, while the dad will give his colorblind gene to all his female children. This means that one out of every two female children will have this trait.

Human birth weight is an example of stabilizing selection, because babies that are too heavy or too light are selected against babies that are typically close to the average weight.

Each parent only carries one type of the allele, so when they give the alleles to their children they would have one allele from each parent. This gives them an genotype of Rr for all of their children. The Rr phenotype is pink.

Hardy-Weinberg is the set of populations that maintain a certain distribution of alleles in a population. In order to maintain this, mating can't choose traits, as that would cause the allele frequency to change over time.
