Curly hair is recessive and straight hair is dominant A woman with curly hair marries a man who is homozygous dominant for straight hair. What are the outcomes for their children?

75% chance of having straight hair and 25 % chance having curly Alleles Curly (woman) Curly Straight Straight Straight (guy) Straight Straight Curly


If straight hair is genetic why do you have straight if none f your ancestors did?

it is because the parents each were heterozyous dominant. meaning each of them had a dominant allele and a recessive allele. the dominant allele would be the curly hair, and the recessive allele would be the straight hair. There would be a 1/4 chance that the child would have curly hair, and a 3/4 chance that they would have curly hair. Say that the Curly hair allele was H and the straight hair allele was h. In order for the parents to have curly hair, they would either have to have an HH gamete or an Hh gamete. Seeing as though the child came out with curley hair, both parents would have to have an Hh gamete. In order to find out the probability, you multiply the parents gametes. (Hh)(Hh). This will give you HH, Hh, Hh, hh. seeing has three of the gametes have the dominant allele, this child will have curly hair, and one is a homozygous recessive, so it will turn out with straight hair.

What is the probability of getting curly hair?

The probability of getting curly hair depends on whether your parents do or not. Hair genes are decided by the mother. So, if the mother has curly hair, more than likely the offspring will as well. If the father has curly hair and the mother does not, the probability is considerably lowered.
