Detailed explanation-1: -In guinea pigs, the allele for black coat color (B) is dominant over the allele for white coat color (b). In an ideal mouse population exhibiting Hardy-Weinberg equilibrium of 31 guinea pigs, 2 are homozygous dominant, 11 are heterozygous, and 18 are homozygous recessive.

Detailed explanation-2: -guinea pigs, black (B) is dominant to brown (b), and solid color (T) is dominant to spotted (t). guinea [ pig which is heterozygous for both traits is mated with brown, spotted pig: The total offspring for several litters are: Solid black =16 Black and spotted = 5 Solid brown Brown and spotted 14.

Detailed explanation-3: -In guinea pigs, the allele for black hair (B) is dominant over the allele for brown hair (b), and short hair (S) is dominant over long hair (s).

Detailed explanation-4: -In guinea pigs, black fur (B) is dominant over white fur (b) and rough four ( R ) is domiant over smooth fur ( r ) . A cross between two Guinea pigs hybrid for both traits (BbRr x BbRr) produces some offsprings that have rough, black fur and some that have somooth, black fur.
