disadvantages of meiosis

Postby lara » Mon Nov 14, 2005 7:48 am

the process of Meiosis takes considerably longer than two mitotic divisions The major features of Meiosis (chromosomal recombination and independent assortment) mean that allelic combinations may be disrupted both within and between chromosomes. Thus, it is likely that high fitness genotypes will be destroyed by the process, and that the mean fitness of the offspring will be lower.

One of disadvantages is that the characteristics of offsprings will be different from their parental. The other, in meiosis probability of mutation is higher than mitosis due to the gene recombination or crossing-over.

Yeah, but isn't that an advantage(higher mutation frequency)?

I would challenge that point. The laws of biology clearly state that the more diversity there is, the healthier a given system will be.

Well, in my point, I meant that by meiosis we will not get offsprings that have similar characteristics to their parents, they are mixture between both parents. If we want to bear offsprings that similar to their parents, just do by mitosis.
