1 Scenario 1: A man and woman have decided to have children but are worried about possible genetic diseases. The couple visits a geneticist to determine what the possible risks are for their future children. The couple discovers that the mom is a carrier, or heterozygous with the diabetes allele and the dad is homozygous dominant, so neither of them have the disease but the mom has one recessive allele. In order to have Diabetes, you have to have two recessive alleles. The following year, the parents are blessed with a bouncing baby boy! What is the correct genotype of the mom? Aa B) AA aa

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. A dominant x-linked allele (B) gives normal color vision but the recessive allele (b) causes red-green color blindness.

They are planning to have another child and you ask for genetic counseling for the following: A. What is the likelihood that another child will have this disease if it is a boy?___ B. What is the likelihood that another child will have the disease if it is a girl? C. What is the overall chance of any child in their family getting the disease?

Question: The disorder: Red-Green color blindness Explain the mode of inheritance of the disorder (recessive, dominant, x-linked, etc.) . Can a person be a carrier of this disorder? • Describe the probability of having a child with the disorder -- give a specific scenario (ex. both parents are heterozygous for the trait) • Describe the symptoms associated with this disorder Explain the prognosis of a person born with this disorder
Mr. Steve W. genetics question Albinism is a recessive autosomal trait for skin pigmentation. Hemophilia is a sex-linked recessive disorder of the blood. assign alleles to the traits A – normal skin pigmentation XH – normal blood a – albino Xh - hemophilia A double heterozygous woman marries a non-hemophilic man and is heterozygous for skin pigmentation. Double heterozygous means heterozygous for both traits. Aa for skin pigmentation and XHXh for blood traits. Therefore, the genotype of the woman is AaXHXh. Non-hemophilic man is XHY and heterozygous for skin pigmentation is Aa. The genotype, therefore, of the man is AaXHY. What is the probability that they will have: a child with normal skin? _____________________ a child with normal blood? _____________________ an albino girl? _____________________ A hemophilic boy? _____________________
