During the formation of gametes - a process called gametogenesis - meiosis is a process which only occurs during this period. Meiosis is a special type of cell division necessary for sexual reproduction.
Meiosis generates variations due to activities like independent assortment of chromosomes, crossing over and random fertilization that occur during the process. Meiosis occurs during sexual reproduction.
meiosis occurs in organisms so that they can reproduce sexually, its a process of cell division during which the nucleus divides into four nuclei, each of which contains half the usual number of chromosomes. and it occurs in both males and females
During meiosis, genetic recombination of homologous chromosomes occurs. So meiosis does result in genetic variation. After prophase I, during which crossing over occurs, every chromosome will have some maternal DNA and some paternal DNA.
THERE IS NO INTERPHASE TWO IN MEIOSIS! There is only one interphase in meiosis and it occurs only in meiosis ONE. Interphase two is not needed because they have already replicated in meiosis one. Replication and growth occurs in interphase and the process is the same in both meiosis and mitosis.
