five medal!!! why meiosis will still increase genetic variation??
Meiosis happens following sexual reproduction. Meiosis contributes to genetic diversity because it allows the cells of the male and female to combine, which results in offspring with unique genes. Producing unique new individuals contributes to genetic diversity.
Meiosis occurs in all organisms carrying out sexual reproduction. Meiosis reduces the number of chromosomes by half, so that when fertilization occurs, the number of chromosomes would be reestablished. Meiosis leads to increased Genetic Variation as 2 divisions produce 4 non-identical daughter cells each containing half the number of chromosomes of the parent cell. This provides an opportunity for new gene combinations to occur in the gametes.
thnx :)
