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 and insects carrying the translocation (as heterozygotes) would die.

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.

(I do not want this answer : 10/16)

Explanation / Answer

The information given is not complete, but i am trying to giva ma best answer . Considering the centromeres are homologous and translocation and is happening on the same chromosome. The transloaction will be of adjacent 2 type. Incase of adjacent translocations the progeny will be of aneuploid. Only incase of non homologous centromeres, the alternate transloaction occurs leading to Orthoploid progeny. In your given scenerio when two aneupliods mate the resulting 50% (1/2 fraction) will be viable of which 16.7 to 20% will be homologous for transloaction. The viablitiy of homologous depend significanty on the breakage points and positions of other genes.
