Wavy hair in mice is a recessive genetic trait. If mice withwavy hair are mated with straight hair (heterozygous) mice, eachoffspring has probability ½ of having wavy hair. Consider alarge number of such matings, each producing a litter of 5offspring. What percentage of the litters will consist of (a) two wavy- haired and three straight-hairedoffsprings? (b) Three or more straight-haired offspring? (c) All the same type (either all wavy or allstraight - haired) offspring?

Simple Dominance with 2 genes
A gene in cats causes them to be black (dominant) or brown
(recessive). A second gene causes cats to be agouti (have stripes
on their hairs) or non-agouti (solid colored hairs).
If you did a dihybrid cross between two black haired agouti
cats, what fraction of the offspring would be expected to have each
phenotype?
If a dihybrid black agouti cat mated with a brown cat that was
heterozygous for the agouti gene, what fraction...
