In a population of mice, the presence of black spots is the result of a homozygous recessive condition. If the frequency of the
Greeley [361]

If A is dominant allele, and a is recessive allel, than:

p is frequency of A allele, q is a frequency of a allele, p2 is a frequency of homozygous dominant genotype, 2pq is frequency of heterozygous genotype and q2 is frequency of homozygous recessive genotype.  

If the population is in Hardy-Weinberg equilibrium; p+q=1

p=0.15 q=1-0.15=0.85

2pq=2*0.15*0.85=0.255~26%

Stolb23 [73]
For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.
