Asexual reproduction relies on a process called mitosis, in which the nucleus of a cell divides to create two new nuclei, each containing an identical copy of DNA. Sign up. At the Smithsonian Visit. With a boy. The centrioles are now at opposites poles in each of the daughter cells.
Just over one percent of the offspring survived. School Board. Correct answer: Twice as many 2n. While some reptiles, amphibians and fish are capable of female-only mating, just one species—the zebrafish—has ever produced offspring without maternal inputand only in a lab.
In each of the two daughter cells the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope. Haploid cells are formed during meiosis and, in humans, produce gametes, which mature into sperm and egg cells.
The division of the cytoplasm Two daughter cells are produced. Threadlike strands of DNA. A second cell division follows: The copies of the chromosomes separate. Explanation : Meiosis is a process that produces gametes in sexual reproduction.
New Research. The disruptive innovation of same-sex reproduction would simply continue this endeavour and provide children to capable parents, as long as it is investigated enough to eliminate risks, made financially accessible and regulated responsibly.
Several of the bimaternal mice even grew up to birth their own healthy pups this time through a more natural means of conception. Example Question 33 : Understanding Meiosis. Unlike in normal cell division mitosis , the genetic material of the original parent cell is divided up twice.
