Salim and Sara are contemplating having children, but Salim’s brother has galactosemia and Sara’s great-grandmother also had galactosemia. Sara has a sister who has three children, none of whom is affected. 1. Construct a genetic pedigree for this family showing the possible genotype of each member.

A certain couple has six children – four boys (ages 2yr, 5yrs, 9yrs and 11yrs old) and two girls (ages 5yrs and 7yrs old). The oldest boy shows the symptoms of Duchenne Muscular Dystrophy (DMD). You are a geneticist and they come to you for advice. What would you tell them about the chances of their other children developing the disease?

Hemophilia is caused by an X-linked recessive mutation in humans. If a man whose paternal uncle (father's brother) was a hemophiliac marries a woman whose brother is also a hemophiliac, what is the probability that their first child will have hemophilia? (Assume that no other cases of hemophilia exist in the pedigree.) 1/3 0 1/8 0 1/4 1/2
A young couple went to see a genetic counselor because each had a sibling with cystic fibrosis. (Cystic fibrosis is a recessive disease, and neither member of the couple nor any of their four parents is affected.) What is the probability that the female of this couple is a carrier? What are the chances that their child will have cystic fibrosis? 3. What is the probability that their child will be a carrier of the cystic fibrosis disease allele?
The gene for polydactyly (P) is autosomal and dominant to normal fingers (p). Hemophilia is sex-linked and recessive (X h ). A man and his wife both of whom are polydactylous and have normal red blood cells have a child who is non-polydactylous and with hemophilia. What are their genotypes?
Kate and her husband are both heterozygous for galactosemia gene. If Kate and her husband have four children, how many of their children are likely to have galactosemia?
Consult Figure 3. This pedigree illustrates the inheritance of Charcot Marie Tooth disease, which is characterized by disorders of the nervous system (OMIM). What is the probability that that next child of the couple marked with an arrow will have Charcot Marie Tooth disease?
A man, Penoy, whose sister died in early childhood from a recessive lethal disease marries a woman Esmae, who has the same family history. Because Penoy has survived beyond childhood, he does not have the disease, but he may be a carrier (i.e. heterozygous, as may also be the case with Esmae). What is the probability that their first child will suffer from the disease? [Hint: first calculate the probability that Penoy is heterozygous; then determine the probability that both parents are carriers. Remember that he has survived to adulthood when calculating this probability].
1. Use the below pedigree chart to answer the following questions about dimples. The Dimple gene controls whether a person has dimples or doesn't have dimples. Dimples is dominant to no dimples. Place the genotypes of each individual below its symbol. male female 7 10 11 male femake Dimples gene (D) Dimples is dominant to no dimples 12 13 14 A) How many family members have Dimples?

. The pedigree below was obtained for a rare kidney disease.a. Deduce the inheritance of this condition, stating your reasons. b. If persons 1 and 2 marry, what is the probability that their first child will have the kidney disease?
Acatalasia is caused by a rare autosomal recessive gene. In heterozygous condition catalase activity is decreased slightly. A woman with a normal catalase activity have a husband with low catalase activity. What is the probability of children birth without anomaly in the family, if grandparents from both sides have reduced activity of catalase? Diagram the cross and mention the genotypes of all individuals in the family?
