Meiosis happens in the reproductive organs and impacts the formation of gametes. The process is divided into 2 types, Meiosis-I and Meiosis-II. Meiosis-I decreases the Chromosome number to half and is also called reductional division. While, on the other hand, Meiosis-II is just like the m...
Meiosis consists of two rounds of division: meiosis I and meiosis II. Each round has a prophase, metaphase, anaphase, and telophase. Meiosis vs. mitosis. Image fromA&P 6. Prophase I is, in my opinion, the coolest phase of meiosis. The 46 chromosomes in your body’s diploid cells are or...

Small regions of sequence homology located at the tips of mammalian X and Y chromosomes where recombination still occurs during male meiosis. Cellular mosaicism The chimeric state of female tissues that results from random X chromosome inactivation, meaning that normal mammalian females have two genetica...
If fertilization occurs, the oocyte completes meiosis II, resulting in the formation of a mature egg and the extrusion of a second polar body. If fertilization does not occur, the unfertilized egg, along with the surrounding follicular cells degenerate. ...
1 Mutation In biology, a mutation is an alteration in the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA or viral replication, mitosis, or meiosis or other types of damage to ...
Both mitosis and meiosis involve phases:Prophase,Metaphase,AnaphaseandTelophase. Although in meiosis, a cell goes through these cell cycle phases twice. Both processes also involve the lining up of individual duplicated chromosomes, known as sister chromatids, along the metaphase plate. This happens i...
