In humans, brown eyes are the dominant feature, and blue eyes are recessive. what kind of eyes will the children of a man and a woman have if one of them has brown eyes and the other has blue

Let the gene that determines the development of brown eyes be C, then the gene for blue eyes is c.

A blue-eyed woman will definitely be cc, because homozygosity is the condition under which blue-eyed will be phenotypically realized. The woman produces eggs c.

A brown-eyed man, due to the dominance of brown-eyed, can be both CC and Cc.

Let’s consider both options.

Male CC, sperm produced by him – C. Possible offspring from his marriage with the above-described woman – Cc – 100% brown-eyed children;

Male Cc, he produces two types of sperm – C and c. Among the offspring from the marriage of such a man with the woman described above, there will be options: Cc (50%) – brown-eyed children and cc (50%) – children with blue eyes.

Answer: If a man is genotypically homozygous (CC), then all children will be brown-eyed; if he is heterozygous for the gene for eye color (Cc), then half of the hypothetical children will have blue eyes, half – brown.
