WebJul 17, 2024 · In anaphase I of meiosis, the following events occur: Chromosomes move to the opposite cell poles. Similar to mitosis, microtubules such as the kinetochore fibers interact to pull the … WebIn the meiosis-II, the two chromatids of A chromosomes and those of a chromosome separate. Thus it becomes clear that both alleles of heterozygote separate during meiosis (gametogenesis) to produce gametes with only one chromosome with either …

WebSporadically, during the father’s meiosis II, the two sister chromatids of the Y chromosome do not segregate, causing the formation of an aberrant sperm having 24 chromosomes and containing two Ys. If this sperm fertilizes a normal egg, the individual will have a 47,XYY karyotype (a condition known as XYY syndrome or Jacobs …
WebDuring meiosis, homologous chromosomes synapse and recombine at sites marked by the binding of the mismatch repair protein MLH1. In hexaploid wheat, the Ph1 locus has a major effect on whether crossover occurs between homologues or between related homoeologues. Here we report that—in wheat–rye hybrids where homologues are …
WebAug 8, 2024 · The human body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment.
