You sample a population of butterflies and find that 42% are heterozygous for a pareticular gene. what would be the frequency of the recessive alle in this population?
cant be determined
i think its .7 but im not sure

can’t be determined
heterozygous individuals have the frequency 2 * p * q
–> 2 * p * q = 0,42
now what are the correct numbers for p and q ? different combinations are possible.
You can’t determine what the frequency of the recessive allele is with only this number.
and even though it would be 0,7, why now q = 0,7 and not p = 0,7 (while the other allelefrequency is 0,3) ?

i hate when theres questions like that, they always trick me
thanks for the help
