Question
Above are the two members of the chromosome 2 homologous pair in a female mouse.
a. specifically, what is the term used to describe the chromosomal abnormality in this mouse?
b. diagram the chromosomes of this female mouse in synapsis at prophase of meiosis I (be sure to include both sister chromotids for each chromosome)
c. assume that a double crossover occured during meiosis in the female mouse. one crossover involved two non-sister chromotids and was between B and the centromere. the second crossover involved the same two non sister chromotids and was between C and D. diagram the gametes that would result from this double cross over event. indicate the probable viability (viable or not viable) of each gamete. be sure to include the different lettered segments, correct alleles, and the centromeres.
Explanation / Answer
a. Translocation is the term used to describe the chromosomal abnormality in this mouse.
b.
