A man homozygous for the perfect pitch trait marries a women without perfect pitch What is the probability that any of their three children will NOT have perfect pitch?

Answer 1

If perfect pitch is dominant you could have this.

PP X pp

Then all of the children will have perfect pitch.

If perfect pitch is recessive, then;

pp X Pp

then there is only a 50% chance of any one child having perfect pitch.

In the future be more precise.

Answer 2

The man's genotype is PP, and the woman's genotype is pp. Their children will all be Pp carriers of the perfect pitch trait. The probability that any of their children will NOT have perfect pitch is 0%, as all will inherit at least one copy of the perfect pitch trait.
