Cats have a gene that codes for the colour of their fur.Suppose that a certain breed of cat can have black, gray, or white fur.
Black fur is dominant, white fur is recessive, and gray fur is intermediate (i.e., cats with gray fur possess one allele for black fur and one for white fur).If agray a cat and a white cat have kittens,what phenotype could the kitten exhibit?
It is actually the opposite. The notochord is a primitive axial skeleton, and in humans, it disappears. It eventually becomes part of the vertebral column, which is the backbone that we have today.
