You have screened for several new recessive mutations in a species of wasp. wasps homozygous for apricot (aa) have pale orange eyes. (wild-type eyes are brown.) wasps homozygous for blunt (bb) have short wings. (wild-type wings are long.) you make a pure-breeding double-mutant (apricot, blunt) line and cross it with wild-type wasps. the f1 is wild-type in appearance. you testcross the f1 dihybrids with the double-mutant line (the "tester" genotype) and obtain four phenotypes in the f2: wild type apricot, blunt apricot blunt determine the following for each f2 phenotype: the haploid genotype of the gamete it received from the f1 dihybrid its full diploid genotype whether the gamete it received from the f1 dihybrid was recombinant (rec) or nonrecombinant (nonrec).

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?
