In a certain breed of dogs, black hair is dominant and brown hair is recessive. if two parents are heterozygous for black hair, what is the probability that their offspring will be black?

There is a 3/4 chance their offspring will be black. If you make a Punnett's (I hope that's how you spell it) square then you will find that one offspring will be homozygous for black hair, two will be heterozygous with black hair, and one will be homozygous with brown hair. Therefore, there's a 3/4 chance the offspring will have black hair. Hope this helped!

There will be a 75% chance of the offspring being black.
