Question by twiins: What role does meiosis have in sexual reproduction? ASAP!!!?
also what role does mitosis have in asexual reproduction?
and in ONLY two sentences how is meiosis in sexual reproduction and mitosis in asexual reproduction similar to a strawberry plant???
and include the websites you got the answers from

Meiosis is the process by which a diploid (2n) organism produces haploid (1n) gametes (eg. sperm and eggs). In humans, which are diploid organisms, we must produce haploid gametes in order to produce offspring with other diploid organisms. If we produced our gametes via mitosis, like all our other cells are produced, then our offspring would end up being 2n + 2n = 4n! This cannot happen, because then that 4n organism would grow, and then have offspring with someone of say, 8n? No! Meiosis is what maintains the proper ploidy in organisms. Because our sperm and eggs are 1n, when they fuse together, the outcome is 1n + 1n = 2n, the same ploidy as human beings. Meiosis also provides genetically different gametes (eg. not all sperm will have the same genetic information), produces genetically different offspring. This is why our children do not necessarily resemble us.
In asexual reproduction, the organism, such as a bacterium, reproduces without a partner. Mitosis is the process by which the cell grows, and you must have growth in order to reproduce alone! For example, by the process of binary fission, a cell will grow a smaller cell off of itself before it grow to a large enough size to be severed from the parent cell. If the cell did not use mitosis, then binary fission would have never been possible, along with any other form of asexual reproduction.
