Guinea pig coat color is determined by a single gene. the allele for black coat color is dominant to brown. in a cross between two black-haired guinea pigs, 20 offspring are born. if both parents were heterozygous, probability would predict that approximately how many of the 20 offspring would have brown hair?

In a cross between two black-haired guinea pigs, 20 offspring are born. If both parents were heterozygous, probability would predict that approximately 1 out of 20 offspring would have brown hair

Explanation:

The two parents crossed were heterozygous dominant black coat color, after crossing 75% gives dominant black color coat while 25% gives only brown coat color homozygous

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
