What is the probability of a women with blue eyes and straight hair man brown curly having kid hair?

To solve this problem, we will need to make some assumptions about the inheritance of hair color and eye color. We will assume that:

* Eye color is determined by a single gene with two alleles, one for blue eyes and one for brown eyes.

* Hair color is determined by a single gene with two alleles, one for straight hair and one for curly hair.

* These two genes are assorting independently.

Based on these assumptions, the probability of a women with blue eyes and straight hair and man brown curly hair having kid hair is as follows:

The probability of the father passing on the brown eye allele is 50%, as he has one brown eye allele and one blue eye allele.

The probability of the mother passing on the straight hair allele is also 50%, as she has one straight hair allele and one curly hair allele.

The probability of the child inheriting both the brown eye allele from the father and the straight hair allele from the mother is 50% x 50% = 25%.

Therefore, the chance of a child with a women with blue eyes and straight hair and man brown curly hair having kid hair is 25%.
