WebFeb 9, 2024 · The process is divided into two types- Meiosis-I reduces the chromosome number to half and is known as reductional division. Meiosis-II is just like the mitotic division. Significance Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. WebA normal karyotype consists of 46 chromosomes, divided into 23 pairs: 22 autosomal and 1 sex chromosome pair (2 X's or one X and Y). Normally, an individual receives one copy of each chromosome from each parent. Abnormal division of a chromosome pair (nondisjunction) can occur during maternal meiosis or during mitosis (after fertil-ization).
