Question

Determine the percent of the population that shows the dominant phenotype if the allele
frequency of the dominant allele is 0.8.

Answer 1

If it is homozygous then 0.8 x 0.8 = 0.64 which is 64%
heterzygous then 0.8 x 0.2 x 2 = 0.32 which is 32%

I am not 100% sure, so wait for other people's answers :)

Answer 2

hmm the answer in my textbook is 96%, but i have no idea how to get there...

Answer 3

yes my answer is also 96%
64% + 32% = 96% :)

Answer 4

cuz both heterozygous and homozygous are dominant, so u have to add them together
the one that is left is the recessive which is 4%

Answer 5

ohhhh that makes sense haha thank you! i didn't go that extra step.

Answer 6

np ;)
