During sexual reproduction, two sex cells fuse to create a fertilized cell with a complete set cCbBlLrR. Anaphase is preceded by metaphase, in which the chromosomes line up along the midline of the cell, and is followed by telophase, which is the final step before the cell . Since the separation of chromosomes into gametes is random during meiosis I this process results in different combinations of chromosomes (and alleles) in each gamete. How many genetically different cells are possible from meiosis? Because the duplicated chromatids remain joined during meiosis I each daughter cell receives only one chromosome of each homologous pair. Select one of the options below as your answer: A.

Anaphase 1: During anaphase 1, homologous chromosomes are arranged in the cell equator. B. For example in humans, sex cells. In this phase, homologous chromosomes are separated and move toward the opposite Poles. Anaphase is dominated by the orderly movement of sister chromatids to opposite spindle poles brought about by the combined action of motor proteins and changes in microtubule length. Through mitosis, two new daughter cells are created from a single parent, each identical to the parent. Yes, B. Click Reset. For example in humans, sex cells A genotype is a list of alleles.

Without a subpoena, voluntary compliance on the part of your Internet Service Provider, or additional records from a third party, information stored or retrieved for this purpose alone cannot usually be used to identify you. Before mitosis, the chromosomes containing DNA are replicated and the replicated sister chromatids remain attached. The mechanics of meiosis II is similar to mitosis except that each dividing cell has only one set of homologous chromosomes. Anaphase I consist of two sets of chromosomes, one from each parent taking place in diploid cells. The answer is c. Anaphase I separates homologous chromosomes and anaphase II separates sister chromatids into daughter cells. Here is a tip: Meiosis I has twice the amount of chromosomes per cell than meiosis II. By shuffling the genetic deck in this way the gametes resulting from meiosis II have new combinations of maternal and paternal chromosomes increasing genetic diversity.
