Explain how meiosis creates genetic diversity
WebThe law of segregation states that the two alleles of a single trait will separate randomly, meaning that there is a 50% either allele will end up in either gamete. This has to do with 1 gene. The law of independent assortment states that the allele of one gene separates independently of an allele of another gene. Web1) Replication beings at origin of replication on chromosome. 2) Soon after, one copy of the origin moves rapidly toward the other end of the cell. 3) Replication continues, one copy of origin at each end of cell. Cell elongates. 4) Replication finishes, plasma membrane grows inwards and new cell wall is deposited. --> 2 daughter cells result.

During meiosis II, the secondary oocyte divides unevenly, with one cell (the ovum) receiving half of the chromosomes and nearly all the cytoplasm and organelles, while the other cell, the polar body, is much smaller and eventually degenerates.
