Meiosis and Sexual Reproduction. Homologous Chromosomes Chromosomes of each pair are similar in length and centromere position Both carry genes controlling.

MEIOSIS: The Production of Sex Cells *Click for Animation*

MEIOSIS (textbook section 3.1 pg 74).  Sexual reproduction produces offspring that is genetically similar, but different from the parents. This is accomplished.

Meiosis Cell division process whereby the number of chromosomes in a diploid cell is reduced by half through the separation of homologous chromosomes.

Chapter 6 Meiosis

Your Cells Somatic Cells – aka body cells Gametes – aka sex cells Most of the cells in your body Undergo mitosis Gametes – aka sex cells Eggs and sperm Allow for passage of genetic information to offspring Undergo meiosis

Chromosomes Humans have 23 pairs of homologous chromosomes One inherited from your mother, the other from your father All but one of these pairs consists of autosomes, or chromosomes that contain genes for characteristics not directly related to sex The last pair is a sex chromosome and it directly controls the development of sexual charateristics
