In a population of tree frogs, the allele that causes yellow eyes (Y) is dominant over the allele that causes orange eyes (y). I
polet [3.4K]

Hardy-Weinberg Principle

Genotype frequency equation

 p^{2} +2pq +  q^{2} = 1

Where p² is the freq of homo dominant genotype, 2pq is the freq of heterozygous genotype and q² is the freq of homo recessive genotype.

Allele frequency equation

p + q = 1

Where p is the frequency of dominant alleles and q is the frequency of recessive alleles.

Yellow eyes in the frog offspring is a phenotype (physical trait) that would be a expressed by a geneotype (YY or Yy). This frequency, 0.85 includes: p² + 2pq

0.85 + q² = 1

q² = 0.15

p = \sqrt{0.15} 

Then p + \sqrt{0.15}  = 1

1 - \sqrt{0.15} = p

p = 0.613

A DNA sample contains 30% cytosine. What percentage of the sample would be thymine?
julia-pushkina [17]

Answer:

30% Thymine

Explanation:

If 30% of Adenine is present, it would be reasonable to assume that 30% of Thymine will be present, as the ratio between the two complementary nitrogenous bases will be roughly equal.

Therefore, that leaves us with 40% between Cytosine and Guanine. Since the ratio between them would be equal, it gives us 20% of Cytosine and 20% of Guanine.

<u>Therefore:</u>

30% of A + 30% of T + 20% of C + 20% of G = 100% DNA
