Meiosis rounds of division
Web2 uur geleden · During meiosis, cells combine one round of DNA replication with two rounds of chromosome segregation, all of which is tightly regulated to ensure that gametes inherit the correct number of chromosomes. Errors in meiosis can lead to aneuploid gametes that cause infertility, birth defects and miscarriages [ 1 ]. WebMeiosis ( / maɪˈoʊsɪs / ( listen); from Ancient Greek μείωσις (meíōsis) 'lessening', since it is a reductional division) [1] [2] is a special type of cell division of germ cells in sexually …
