Question

It has been proposed that insect pests could be controlled by introducing translocations into wild populations. According to the proposal, 50% of the offspring of crosses between wild-type insects arid insects carrying the translocation (as heterozygotes) would die. Part A Assume that the parents have the same chromosomes involved in the translocations and that the translocation breakpoints are not lethal. Also assume that for the translocation chromosomes involved, chromosomes with homologous centromeres never segregate together during meiosis. What proportion of the progeny of crosses between two such translocation-carrying insects would die? Enter your answer as a reduced fraction.

Explanation / Answer

Answer:

When two nonhomologous chromosomes mutate by exchanging parts, the resulting chromosomal rearrangements are translocations.

The 10/16 of the progeny of crosses between translocation-bearing insects would die.
