In morgan's testcross of a gray-bodied, long-winged heterozygous female drosophila with a homozygous recessive black-bodied, vestigial-winged male, the following offspring were obtained:
1) 965 gray body,
2) long wing;
3) 944 black body,
4) vestigial wing;
5) 206 gray body,
6) vestigial wing;
7) 185 black body,
8) long wing.
9) focusing only on the recombinant classes (gray body, vestigial wing and black body, long wing),
10) the numbers of offspring of each type are similar (206 and 185).
what accounts for the similar number of offspring of each recombinant phenotype?

Mutations associated with albinism affect proteins involved in synthesis

Coat color in cats is determined by genes at several different loci. at one locus on the x chromosome, one allele (x ) encodes black fur and another allele (xo) encodes orange fur. females can be black (x x ), orange (xoxo), or a mixture of orange and black called tortoiseshell (x xo). males are either black (x y) or orange (xoy). bill has a female tortoiseshell cat named patches. one night, patches escapes from bill\'s house, spends the night out, and mates with a stray male. patches later gives birth to the following kittens: one orange male, one black male, two tortoiseshell females, and one orange female. what are the genotypes of patches, the stray male, and the kittens?
