Question

In fruit flies (drosophila melanogaster) there is a dominant allele for red eyes and a recessive allele for white eyes. These alleles are located on the x chromosome. If a heterozygous red-eyed female is mated with a white-eyed male, what percentage of the offspring are expected to be white-eyed females? ( enter the number only without the percent sign. For example, enter 100% as 100 and enter 12.5% as 12.5 )

Answer 1

Answer:

50

Explanation:

For example

Rr(female heterozygous red eyed)

rr(white eyed)

Rr×rr

50%Rr(female heterozygous red eyed)

50%rr(females white eyed)

Expected females white eyed in 100 fruit flies is 50

Hope you got it
