BRCA1 is a tumor suppressor gene. BRCA1* is the symbol for the non-mutant or wild-type form of the gene. Part1. A woman has inherited a mutant BRCA1 allele. Her genotype is BRCA1*/BRCA1". How many copies of the wild-type BRCA1+ allele and the mutant BRCA1 allele would you expect to find in each of her non-cancerous cells? Part 2. How many copies of the wild-type BRCA1* allele and the mutant BRCA1¯ allele would you expect to find in each of her cancerous cells? Part 3. Describe whether mutant BRCA1° acts in a recessive or dominant fashion in a celI. Part 4. If you analyze this woman's eggs, how many copies of the wild-type BRCA1* allele and the mutant BRCA1¯ allele would you expect to find in each egg? What is the chance that she passes on the mutant form of BRCA1 to her egg and then to potential offspring?
