In Drosophila melanogaster, white eyes (w) is an X-linked recessive mutation. Normal eyes are red (W). At the autosomal wing shape locus, normal shaped wings (VG) are dominant to vestigial wings (vg). The following cross was made: XWXw VGvg x XWY VGvg. What proportion of the progeny from this cross will be females with red eyes and vestigial wings? Write your answer as a numerical value rounded properly to 4 decimal digits. Do not write the answer as a fraction or percentage.

In seals, the gene for whiskerlength has 2 alleles. The dominant allele … W (long whiskers)The recessive allele … w (short whiskers)The expression of the trait is based on simple orcomplete dominance.If a homozygous dominant female mates with a heterozygousmale, what percentage of the offspring can be expected to have shortwhiskers?Youranswer:_____________________________If a homozygous recessive female mates with a heterozygousmale, what percentage of the offspring can be expected to have shortwhiskers?Youranswer:_____________________________
