In cattle, black coat (R), is dominant to red coat (r). Hornless (H), is dominant to horned (h). A certain bull was mated to four cows. Find the genotypes of all cattle mentioned.

Rabbit fur is determined by multiple alleles. Solid color is controlled by the Ic allele, the chinchilla by the Ich allele, the Himalayan by Ih and the albino by i. The dominance hierarchy of these alleles is Ic> Ich> Ih> i. Write the gametes that a HIMALAYAN rabbit would form [x1]

Please read the scenario below, and then answer the question (in bold) that follows. In cats, the allele (B) produces a black coat color and the allele (b) produces a yellow coat color. These alleles are incompletely dominant to each other. A heterozygote produces a tortoise shell coat color. The alleles (B) and (b) are also sex-linked (i.e., they are carried on the X chromosome), and cats possess an XX-XY sex determination system, like humans. If a female cat with a tortoise shell coat mated with a male cat who had a yellow coat... What percentage of their offspring will have tortoise shell coats?   a. 0%   b. 25%   c. 50%   d. 75%   e. 100%

Give typed explanation  In pea plants, the tall allele (T) is dominant to the dwarf allele (t) and the yellow pea color allele (Y) is dominant to the green pea color allele (y). Cross TtYy with Ttyy. What would be the genotype and phenotype ratios in their offspring? (Please include the gametes produced by each parent.)
