For example, if a cell was undergoing … Web5 de abr. de 2024 · Meiosis is a precise and tightly regulated process of sexual reproduction that increases biodiversity and survival in eukaryotic organisms. A lot can go wrong during the stages of cell division. Some errors may be inconsequential or confer an advantageous trait. However, missteps can also result in genetic defects, chromosomal abnormalities ...
WebInstead of assorting independently, the genes tend to "stick together" during meiosis. That is, the alleles of the genes that are already together on a chromosome will tend to be passed as a unit to gametes. In this case, the genes are linked. For example, two … Web3 de ago. de 2024 · The crossing over happens during meiosis, a cellular process where a cell divides in two, resulting in an egg or sperm. During meiosis, the two chromosomes swap a few genes, so the resulting ...
WebDuring mitosis the sister chromatids separate and go to opposite ends of the dividing cell. Mitosis ends with 2 identical cells, each with 2N chromosomes and 2X DNA content. All eukaryotic cells replicate via mitosis, except germline cells that undergo meiosis (see below) to produce gametes (eggs and sperm).
