Question

An organism has alleles R₁ and R₂ on one pair of homologous chromosomes, and it has alleles T₁ and T₂ on another pair. Diagram these pairs of homologs at the end of metaphase I, the end of telophase I, and the end of telophase II, and show how meiosis in this organism produces gametes in expected Mendelian proportions. Assume no crossover between homologous chromosomes.

Accepted Answer

Hello, everyone and welcome to today's video. So during meiosis two blank segregates which result in the production of blank cells. Well, remember that during meiosis, this is a process that is going to be producing gametes and meats or haploid, their haploid cells. So that is what we're going to be inputting here at the end. And because of that, we're going to be able to cancel out answer choices A and C which are homologous chromosomes and deploy s through chromatid and deploy because they are not haploid as we were able to get here before observing them. So we're going to focus on answer choices B and D which are homologous chromosomes and haploid ancestor chromatid and haploid. Well, remember that meiosis one is a process that is going to desegregating homologous chromosomes at this point. This is the beginning of meiosis and nothing has been segregated. So we're able to segregate the homologous chromosomes that exist in the cell. However, during meiosis too, this has already occurred. So we cannot segregate these homologous chromosomes again. Instead, we're going to be just getting these single single chromosomes that we have in the cells and we're pulling them apart to obtain the sister chromatid. So we are pulling apart or segregating sister chromatid into the different gammit cells that are haploid. So the correct answer choice here is going to be answer choice. The so the two ces chromatid segregate which results in the production of halo cells. I really hope this video helped you and I hope to see you on the next one.
