- In man, assume that spotted skin (S) is dominant over non-spotted skin (s) and that wooly hair (W) is dominant over non-wooly hair (w). Cross a marriage between a heterozygous spotted, non-wooly man with a heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring. In horses, black is dependent upon a dominant gene, B, and chestnut upon its recessive allele, b. The trotting gait is due to a dominant gene, T, the pacing gait to its recessive allele, t. If a homozygous black pacer is mated to a homozygous chestnut trotter, what will be the appearance of the F1 generation?In cats, the allele (B) produces black color but (b) producesyellow color. These alleles are co‐dominant to each other. Aheterozygote produces a tortoise‐shell color. The alleles (B)and (b) are sex‐linked as well. Cross a tortoise‐shell femalewith a yellow male. What percent of their offspring will be yellow? What percent of their offspring will be black? What percent of their offspring will be tortoise shell?Use a punnett square in fruit flies, red eyes (r) are dominant to pink eyes (r). what is the phenotypic ratio of a cross between a heterozygous male and a pink-eyed female

How many offspring will be non-spotted, non-wooly mammoth? How many offspring will be spotted, wooly mammoth? How many offspring will be non-spotted, wooly mammoth?In seals, long whiskers (W) are dominant over short whiskers (w). What are the genotypic and phenotypic ratios for the offspring produced by mating a seal that is homozygous recessive with one that is heterozygous?(Reask) An aquatic arthropod called a cyclops has antennae that are either smooth or barbed. The allele for barbed (B) is dominant over smooth (bb). In the same organism, allele for non-resistance (N) to pesticides is dominant over resistance (n) to pesticide. What is the genotypic ratio of the offspring from a cross of Bbnn and bbNn cyclops? What would be the resulting phenotypic ratio if cyclops with genotypes BBnn x Bbnn mated?

- Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele have sharp spines, whereas homozygous recessive cactuses have dull spines. At the same time, a second gene, N, determines whether or not cactuses have long or short spines. Homozygous recessive cactuses have short spines. A cross between a homozygous sharp-long cactus and a dull short-spined cactus would produce what percentage of sharp-long cacti?
