Question

A fly has two alleles for the color of its eyes. the green allele is recessive, and is represented by q. the blue allele is dominant, and is represented by p. if 71 of 100 organisms are green, what is p

Answer 1

Answer:

$p = 0.29$

Explanation:

According to the Hardy Weinberg’s equation –  

The sum of frequencies of all the allele with in a given population is equal to one around the locus.  

Thus, if p is frequency of trait “A” and q is frequency of trait “B”, then the sum of the allele frequencies i.e p and q is 1

$p + q = 1$ -------------------- Equation (a)

So, if 71 out of  100 organisms are green, then q would be

$= \frac{71}{100}$

$= 0.71$

Putting the value of q in equation "a" we get -

$p + 0.71 = 1\\p = 1 - 0.71 \\p = 0.29$

Answer 2

Answer:

0.16
