Week2+-+Meiosis+and+Chromosomal+errors

This week you are learning about the mechanisms of cell division by mitosis and then meiosis. In meiosis homologous chromosomes come together, then separate again. In the end of meiosis the daughter cells end up with half the chromosomes of the mother cell. Since this happens to both sperm and egg, when they unite, a normal chromosomal number is resumed.

The article for this week addresses the fact that women at age 35 and above, are more at risk for having children with chromosomal disorders.

Open the article "Women's chromosome division different from men's" that can be found in []. Answer the related questions in the discussion board (upper right hand side). UserID: mxd0543@lausd.net Password: Kennedy (Case sensitive)
