1. Three alleles exist for coat color in rabbits: Cp, Ct, and Cz. A male Cp/Cz i

Question

1. Three alleles exist for coat color in rabbits: Cp, Ct, and Cz. A male Cp/Cz is crossed with a female Ct/Ct. Occasionally some rare genotypes occur. For each of the following rare genotypes, explain how they occurred: state which meiotic stage nondisjunction occurred and in which parent (male vs. female) the event occurred (example: female meiosis I). What caused the following rare genotype: Cp/Cz/Ct

Explanation / Answer

Solution 4. Interspecific hybridisation

Solution 5. It is a type of substitution mutation. As we know substitution is further divided into transition and transversion, so the above example is type of Transition mutation.

Solution 6.

XO represents monosomy, so Turner syndrome is an example of monosomy condition.

XXY represents trisomy of sex chromosomes so Klinefelter syndrome is an example of trisomic condition.
