Question
1. A new species of animal is discovered. If a diploid cell from this animal has 82 chromosomes in each of its body cells, how many cells will each gamete have? a.) 82 b.) 41 c.) 20 d.) 164 2. What is the term to describe the number of chromosomes in a gamete? a.) diploidb.) haploid c.) multiploid 3. Women can inherit alleles of a gene called BRCA1 that puts them at higher risk for breast cancer. The alleles associated with elevated cancer risk are dominant (B allele). Of the genotypes listed below, which carries the lowest genetic risk of developing breast cancer. a.) BB b.) Bb c.) bb d.) All carry equal risk 4. In humans, "unattached" earlobes are dominant over "attached" earlobes. If there exists a 50 percent chance that a child will have unattached earlobes, and E and e are used as symbols for the earlobe phenotype alleles, then the parental genotypes must be: a.) ee and ee b.) Ee and ee c.) EE and Ee d.) Ee and Ee. e.) EE and ee 5. In humans, "unattached" earlobes are dominant over "attached" earlobes. Widow's-peak hairline is dominant over non-widow's-peak hairline. Use E and e for the earlobe phenotype alleles and Wand w for the hairline phenotype alleles. A woman with unattached earlobes and a widow's peak and a man with attached earlobes and a widow's peak have a child. The child has attached earlobes and a non-widow's-peak hairline. What are the genotypes of the mother and father? a.) Mother EEWW and Father eeww b.) Mother EeWw and Father eeWw c.) Mother EeWw and Father EeWW d.) Mother EeWw and Father eewwExplanation / Answer
Answer- 41 gametes in each cell
Because at, the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes
Answer- 2 Haploid
Haploid describes a cell that contains a single set of chromosomes.
Answer-3 bb
Because dominant allele has the risk of cancer development. Both BB and Bb have chances of cancer development i.e both carries dominant alleles but bb have only recessive allele
