me astigmatism and non-red hair are produced by a different pair of completely dominan genes. Hence, astigmatic persons whose hair is not red are A-B- How often in families of four children where the parents are both heterozygous for astigmatism and heterozYgous for hon red hair would you expet 2 astigmatic red haired girls and 2 non astigmatic brown haired boys?
