Question

HELP PLEASE! MEDAL GIVEN!

In a population of grasshoppers, the color green (G) is completely dominant over the color brown (g). If 23% of the population is brown, calculate the percentage of the population that is expected to be heterozygous (Gg).

50 percent

47 percent

77 percent

35 percent

Answer 1

I don't think its 77 percent as http://openstudy.com/study#/updates/508b1975e4b077c2ef2e7671 says otherwise

Answer 2

but i don't know the answer

Answer 3

f (gg) =q ^2 = 0.23 so f(g) = q= 0.48

p= 1-q = 0.52

Frequency of heterozygotes is 2pq = 0.5 = 50%

Answer 4

OK, thank you so much!

Answer 5

Welcome!
