Question

Albinism in humans is caused by homozygosity for mutant recessive alleles of the TYR gene, which is located on chromosome 11. Alkaptonuria in humans is caused by homozygosity for mutant recessive alleles of the HGD gene, which is located on chromosome 3. Suppose that a man and a woman who are each heterozygous carriers of mutant recessive alleles of both the TYR and HGD genes have five children. What is the probability that at least one of their children will have albinsim and/or alkaptonuria? 0.06 0.22 0.44. 0.76 0.78 0.94

Explanation / Answer

D. 0.76

Alkaptonuria in humans is caused by homozygosity for mutant recessive alleles of the HGD gene, which is located on chromosome.

Segregation is the separation of alleles during meiosis, while independent assortment states that a member of one gene pair has an equal and independent opportunity of segregating with either member of another gene pair.
3) When the probability value is less than 0.06
