Here is a pedigree from a family with ahigh prevalence of breastcancer. dx means the age at diagnosis.The letters A-E are haplotypes (alleles).dx51[D-]dx 46BC☑7dx58BD(C-)77CDdx 44BDACहेdx 48 42 dx3854dx33BCBCBDDABCd.) Are there any individuals in thepedigree you might expect to havebreast cancer, but do not? If so,identify the people (using the standardnotation for identifying people on apedigree) and suggest an explanation.

A SNP marker is found linked to the cystic fibrosis gene. Cystic fibrosis is an autosomal recessive disease. A couple plans to have children together and both are carriers for the cystic fibrosis gene but do not have the disease themselves. They are both A1/A2 at the SNP and the A2 allele is linked with the allele causing cystic fibrosis. Assuming no crossing over between the SNP and the disease gene, what genotypes in the offspring could result that would cause cystic fibrosis? O A1-cf, A1 - cf O A2-cf, A2 - cf O A1 - CF, A1 - CF O A1 - CF, A2 - cf
Complementation tests are performed in the (F1/F2/dominant/recessive/affects/does not affect) progenyof two (F1/F2/dominant/recessive/affects/does not affect) true-breeding mutants.If the two mutants are affected in different genes, the map distance between the twogenes (F1/F2/dominant/recessive/affects/does not affect) how often complementation is observed.
Retinoblastoma can be seen as a familial cancer, inherited in an autosomal recessive manner (RB-/RB-), individuals heterozygous for the RB+ and RB- alleles can develop tumor as a result of… A mitotic crossover that leads to homozygosity for RB+ in some cells and RB- in other cells A meiotic mutation in the RB+ allele that leads to homozygosity for RB+ A somatic mutation in the RB- allele that leads to homozygosity for RB+ The fact that RB- is dominant to RB+

Duchenne’s muscular dystrophy (DMD) is an X-linked disease that causes progressive muscle weakness and is often fatal. “XD” represents the wild type allele, and “Xd,” the mutant allele. Jonah is XDXd Y and his brother Pete is Xd Y. Jonah and Pete BOTH have DMD of equal severity and phenotypes. You might have thought Jonah’s DMD would be less severe given his genotype. To better understand the situation, you investigate Jonah’s Xist chromosome region in his defective muscle cells. Which of the following is consistent with his phenotype? (Select all that apply.) The Xd-containing chromosome is inactive in defective muscle cells. The XD-containing chromosome has a methylated Xist promoter. The XD-containing chromosome has an unmethylated Xist promoter. The Xd-containing chromosome is active in defective muscle cells.
II. Given the following pedigree below, use Punnett squares for each of the following possibilities: a) Autosomal recessive and b) Autosomal dominant in order to determine what is the mode of transmission of this trait. Disease allele = a or A, depending on mode of transmission of the disease respectively. Your Punnett squares should reflect what you see in generation II. Circle the mode of transmission.
