Organism reproduction with an emphasis on meiotic cell disivion

Organisms can reproduce by two processes, a interior and sexual reproduction. Asexual reproduction is the production of offspring by a single parent. Offspring produced asexually inherit their deoxyribonucleic acid from exclusively mavin parent and are ancestralally identical to that parent. productive processes that involve obtaining communicable information from two parents that involve the incumbrance of a sperm cellatozoon and an ballock is called sexual reproduction. A sperm and bollock individually carry adept set of genetic information. Egg and sperm cadres are collectively known as gametes. Gametes are formed by a kind of booth division called mitosis. The fusion of a sperm from the father and the egg cells from the mother is known as fertilization. The toping fertilized egg is called a zygote, and is diploid. The zygote consists of two haploid sets of chromosomes, one from the mother and one from the father. In the meiotic process of cell division the num ber of chromosomes in a cell reduces from diploid to haploid. Meiosis consists of two consequent stages of cell division, called meiosis I and meiosis II. As a result of meiosis four daughter cells (gametes) are produced with however half(prenominal) as many chromosomes as the starting cell. Each gamete has one member of each homologous chromosome pair. There are cardinal stages of meiosis. iv of stages are in meiosis I, the physical system of the division where the homologous chromosomes separate. A homologous chromosome is two chromosomes that defy up a matched pair in a diploid cell. They are the similar length, have the same centromere position, and spotting pattern and let genes for the same characteristics. Like mitosis, the stages of meiosis I are preceded by an interphase where the number of chromosome replicate. Prophase I of meiosis is the about complex phase and takes up 90% of the time it...
