Consider a female Drosophila with the following X chromosome genotype:

The recessive alleles w and dor cause mutant eye colors (white and deep orange, respectively). However, w is epistatic over dor; that is, the genotypes w dor / Y and w dor/ w dor have white eyes. If there is 40 percent recombination between w and dor, what proportion of the sons from this heterozygous female will show a mutant phenotype? 

What proportion will have either red or deep orange eyes?
