Apopulation is in hardy-weinberg equilibrium with respect to a gene, "yellow," which has 2 alleles, y and y. y, the wild type allele, is completely dominant to y, and results in green pigment; yy results in yellow pigment. the frequency of the yy homozygote is 0.09. the frequency of the y allele is ; the frequency of the y allele is ; the frequency of the yy homozygote is ; the frequency of the yy heterozygote is

The frequency of the Y allele is 0.7

The frequency of the y allele is 0.3

The frequency of the YY homozygote is 0.49

The frequency of the Yy heterozygote is 0.42

Explanation:

According to Hardy-Weinberg Equilibrium,

p + q = 1

p² + 2pq + q² = 1

where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of dominant homozygous genotype

2pq = frequency of heterozygous genotype

q² = frequency of  recessive homozygous genotype

Here,

yy = q² = 0.09

frequency of y allele = q = √0.09 = 0.3

frequency of Y allele = p = 1-q = 1-0.3 = 0.7

p² = YY = (0.7)² = 0.49

2pq = Yy = 2 * 0.7 * 0.3 = 0.42

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
