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…

interpret using the punnett square below to both sets of parents (Parents A , Parents B, & Parents C).based on your results of filling in the boxes. What are the chances Parents A, Parents B, and Parents C will have a child with Sickle Cell? What are the chances the child will be a carrier for Sickle Cell?

A child with Type O blood is born to a mother with Type B blood. What is the genotype of the child? What is the genotype of the mother? What are all the possible genotypes the father could be?

Kara is B-positive and her father has A-negative blood. Kara marries Ryan, who is A-negative. Ryan’s father has O-positive blood. (e)What are the phenotypic ratios of blood types (for both the ABO gene and Rh gene) that would be expected among their children? (Show your work in a Punnett square below!)

Complete Punnett square C for an individual with an AO genotype that mates with another AO genotype individual.

Please use instructions from above Hemophilia is an x-linked disease of the blood. What is the probability of producing an unaffected son by a father who is unaffected and a mother who is a carrier of hemophilia?

Basha: A blood type, blue eye color, normal skin condition, carrier of cystic fibrosis gene, and carrier of hemophilia gene Popoy: B blood type, has brown eye color, normal skin condition, carrier of cystic fibrosis gene and negative to hemophilia. What is the probability that the offspring will have/ be: A. a girl with all the same phenotype as her mother. B. 2 girls with neither the blood type of the parents.

Describe the phenotype of individuals who inherit two copies of the HbS allele-Sickle Cell Disease. ( find a source to support the information)
