WebFeb 3, 2016 · Mitosis is the mechanism of asexual reproduction. Meiosis provides the variation that sexual reproduction requires. A single cell dividing by mitosis is an example of asexual reproduction--you now have two identical daughter cells (usually thought of as diploid 2n) from one single mother cell. Meiosis is important to sexual reproduction, … WebJan 1, 2009 · An alternative view is that the initial benefit of meiosis was enhanced repair of DNA damage via recombination (Bernstein 1977; Bernstein et al. 1988). The need for …

Meiosis, Genetic Recombination, and Sexual Reproduction

WebMeiosis is a process where germ cells divide to produce gametes, such as sperm and egg cells. In prophase I of meiosis, chromosomes condense and homologous recombination takes place, leading to genetic variation through chromosomal crossover. This forms a tetrad, which is made up of four chromatids (two sister chromatids per chromosome). http://www.science-mathematics.com/Biology/201205/32159.htm hemodialysis cost per session

WebBudding is a form of asexual reproduction that results from the outgrowth of a part of a cell or body region leading to a separation from the original organism into two individuals. Budding occurs commonly in some invertebrate animals such as corals and hydras. In hydras, a bud forms that develops into an adult and breaks away from the main body, as … WebHow does meiosis most benefit a species? answer choices It increases mutations It increases genetic variation It decreases the number of chromosomes an organism will receive It increases the number of chromosomes an … WebMost fungi and algae employ a life-cycle strategy in which the multicellular “body” of the organism is haploid. During sexual reproduction, specialized haploid cells from two individuals join to form a diploid zygote. The zygote immediately undergoes meiosis to form four haploid cells called spores ( Figure 7.2 b ). hemodialysis cost per treatment

"WebThe human body uses both meiosis and mitosis as methods of cell division. A single cell splits into two identical daughter cells during the process of mitosis, each of which has the same number of chromosomes as the parent cell. It takes place in somatic cells, which are the body's non-reproductive cells, and is in charge of growth and repair. " - How does meiosis most benefit a species
