Answer #1

a)dominant alleles are those which expresses its traits even in presence of an alternative allele i.e in heterozygous condition. now, here when cross is done in white and black cat they gave  f1 generetion (i.e first filiial generation ) black cats here the black color is dominant over white color.

b) the recessive allele white is designated with small letter whereas dominant allele is designated by capital letter so here dominant allele is black designated by 'B' whereas recessive allele white is designated as 'b'.

c) genotype of black cat is BB or Bb whereas for white is bb and that of f1 is Bb.

d)

    In hogs, and allele that produces a white belt around the animals body (W) is dominant over its allele for a uniformly colored body (w). The dominant allele of another gene (F) produces a fusion of the two hoofs on each foot. Suppose a uniformly-colored hog homozygous with fused hoofs is mated with a normal-footed homozygous for the belted character. what are the genotypes of the parents? belted parent: Uniformly-colored parent: What are the genotypic and phenotypic ratios in the...

    Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

    Just answer Part B While working with a type of beetle that is normally smooth, large, and white, you discover three mutations that lead to the recessive phenotypes bumpy, small, and grey, respectively. You cross true- breeding smooth white beetles to true-breeding bumpy grey beetles and get all smooth white F1 beetles. Then you cross the F1 beetles to true-breeding bumpy grey beetles and, after analyzing 800 F2s, calculate a map distance of 5 M between the smoothness and color...
