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 … WebDuring meiosis, homologous chromosomes pair up and exchange genetic material in a process called crossing over. This creates new combinations of alleles on each chromosome. During meiosis I, homologous pairs of chromosomes separate and migrate to opposite poles of the cell, resulting in two daughter cells with one …

WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a … WebThe homologous chromosomes separate during meiosis I, but the separation of the pairs of homologs is independent of other homologs. As an example in the figure below, for a cell with two pairs of chromosomes (2n=4), there can be four possible combinations of the four chromosomes.
