Question
Use the appropriate answer to determine the following genetics problems. a.YX b. Y, X C. I^A, I^B d. I^A I^B e. Xx, Zz f. Xx Zz g. XZ, Xz, xZ, xz h. Aa i. A, a Give genotype(s) of gametes which could be produced by an individual with a genotype of I^AI^B. Give genotype(s) of an individual which produced gametes of A and a genotype Give genotype(s) of an individual which produced gametes of Y and X genotype. Give genotype(s) of gametes which could be produced by an individual with a genotype of XxZz.Explanation / Answer
Please find the answers below:
Answer 19: When an individual has a genotype IAIB, he/she can produce two types of gametes having genotype IA and IB. These gametes will correspond to phenotypes A and B respectively. Thus,choice c is correct.
Answer 20: When an individual produces gametes of genotype A and a, he/she must have genotype containing both these alleles, i.e. IAIa. Thus choice i is correct.
Answer 21: For an individual to produce gametes X and Y, the genotype must be containing both these alleles.Thus, choice a is correct.
Answer 22: For an individual with genotype XxZz, he/she can produce four types of gamets since there are 2*2 =4 possible combinations of gamete formation. Thus, choice g is correct.
