What Is Metaphase I Homologous Chromosomes?

Homologous chromosomes are alike in size and structure. They carry the same type of information but not necessarily the same specific information. In sexually reproducing animals, one homologue comes from the female parent and one from the male parent via fertilization.Genetic recombination is different combination of chromosomes of offspring than their parents. Two ways this can occur during meiosis is independent assortment and through crossing-over.After crossing –over occurs, sister chromatids are non- identical. Homologous chromosomes don’t have the same exact information, it means that when material is exchanged between non-sister chromatids sister chromatids are no longer identical.In metaphase I homologous chromosomes line up and the side of is randomly determined. …show more content…
There are two chromosomes in each pair, on average, each daughter cell will end up with 50% maternal and 50% paternal chromosomes. The positioning of homologous pair members is decided each time and this process is recurring with every meiosis and crossing-over.Two daughter cells, each haploid, containing a single copy of each chromosome that still has sister chromatids linked by a centromere.The end products are four cells, each with a single copy of each chromosome and no chromatids present.During meiosis one egg cell and two to three polar bodies are produced. Polar bodies get the excess chromosome, while the egg gets almost all of the cell's cytoplasm. The extra cytoplasm in the egg provides nutrients for the developing
