In humans, freckles are dominant to no freckles. A man with freckles is married to a woman with freckles, but the children have no freckles. What's the reason?
2 14045In horses, B = black, b = brown, T = trotter, t = pacer. A black pacer mated to a brown trotter produces a black trotter offspring year after year. What are the probable genotypes?
1 6203In human beings, brown eyes are usually dominant over blue eyes. Suppose a blue-eyed man marries a brown-eyed woman whose father was blue-eyed. What proportion of their children would you predict to have blue eyes?
1 20273A brown-eyed man whose father was brown-eyed and whose mother was blue-eyed married a blue-eyed woman whose mother and father were both brown-eyed. The couple has a blue-eyed son. What are the genotypes of all individuals?
1 10042In hogs a gene that produces a white belt around the animal's body is dominant over its allele for a uniform body. Another independent dominant gene produces fusion of the hoof (syndactyly). Suppose a uniformly colored hog homozygous for syndactyly is mated with a normal footed hog homozygous for the belted character. What would be the phenotype of the F1? If the F1's interbreed, what would be the phenotypic ratio of the F2?
5698For each of the following, state whether it is a gamete or a genotype of an individual a) TT b) Tg c) IcCC d) TW
2 4627The gene for tallness (T) is dominant over the gene for shortness (t) in pea plants. A homozygous dominant pea plant is crossed with a heterozygous pea plant, and 200 seeds are produced. Approximately how many of these seeds can be expected to produce plants that are homozygous dominant?
3 11821People who can roll their tongues contain a dominant allele for tongue rolling. If people do not contain the tongue rolling gene, then they cannot roll their tongue no matter how hard they try. Consider the following situation: If a homozygous dominant tongue roller mates with a homozygous recessive non-tongue roller, then what is the probability of the offspring inheriting the tongue rolling gene?

In horses coat color is dependent upon genes as follows: A_B_ results in bay, aaB_ in black, A_bb in chestnut, aabb in liver. In addition, palimino is derived by Dd with chestnut. A palimono stallion (DdAAbb) is crossed with a palimino mare (DdAAbb). What percent of the offspring will be palimino?
