. Two mothers give birth to sons at a busy hospital. The son of the first couple has hemophilia, a recessive, X-linked disease. Neither parent from couple #1 has the disease. The second couple has an unaffected son, despite the fact that the father has hemophilia. The two couples challenge the hospital in court, claiming their babies must have been swapped at birth. You must advise as to whether or not the sons could have been swapped. What would you say? キ 5. In a dispute over parentage, the mother of a child with blood group O identifies a male with blood group A as the father. The mother is blood group B. Draw Punnett squares to show possible genotype/phenotype outcomes to determine if the male is the father and the reasons (if any) for further dispute:

Hemophilia is an x-linked disease in which the blood does not clot normally; it is sometimes called "bleeder's disease." Hemophilia is caused by a recessive allele (h). The dominant allele (H) produces blood that clots normally. What is genotype of a man who is a hemophiliac? What is the genotype of a man with normal blood clotting? What is the genotype of a woman with normal clotting blood if her father was a hemophiliac? If a man with normal clotting blood and a heterozygous woman have children together, what would you expect for the genotypes and phenotypes of the children? 13.

reference text Ph.D Fernando, Harvard Professor of Genetic Epidemiology, knows a thing or two about Twins. He must know as he is head of the Twin Research Department where he works with about 3,500 pairs of identical twins, researching the influence of a person's genes on everything from the probability of being obese, whether or not they have religious beliefs, and, how, do they fall into sentimental issues. Anyone who is a twin, or who has ever met a pair of identical twins, can attest to how remarkably similar they are to each other, even in the rare cases of adopted twins raised in separate homes.A recent article begins with an introduction to two middle-aged twin sisters called Susan and Polly, one of the pairs of twins in the study group of the Department of Research of Harvard. Although they were treated almost as a single person growing up, with cuts from identical hair and clothes, the twins began to diverge in their teens as they they gained the freedom to make their own…

Y-linked traits are passed from the father to son, without the occurrence of genetic recombination. 9. Somatic mosaicism results to abnormalities based on the amount and distribution of normal cells while gonadal mosaicism affects the germline tissues leading to a new dominant mutation. 10. A test cross is done to determine which allele is dominant and which is recessive.
