ANTHRO 101 Lecture Notes - Lecture 10: East Los Angeles College, Down Syndrome, Gametocyte
Document Summary
All species have different number of chromosomes. Members of the same pair are homologous chromosomes. Homologous chromosomes have the same gene loside. One chromosome codes for example, ptc tasting and other second chromosome also codes for ptc tasting. Even though ptc tasting is present, there are different variations. E) restating principle of segregation and independent assortment that causes ptc tasting, which are alleles. 50/50 chance of which way the allele goes. Mendel didn"t know that when you make sperm. With every chromosome there is a 50/50 chance that they will go to either gametes. There is no specific gamete that they need to go to. Spermatocyte: are a type of male gametocyte in animals. They derive from immature germ cells called spermatogonia. Oocyte: a cell in an ovary that may undergo meiotic division to form an ovum. Processes that speak to how organism, cells reproduce themselves. Parent cell divides into 2 daughter cells.
