Why meiosis 1 is called heterotypic and meiosis 2 is known as homotypic.
The first reductional of two nuclear divisions in meiosis in which the number of chromosomes is halved. The second equational is a homotypic division.
Meiosis 1 is called heterotypic because in this chromosome number reduces to half crossing over takes place between pair of homologous chromosomes.
whereas in meiosis 2, the chromosome number remains same so it is called homotypic division.
