How Mistakes in Cell Division Can Result in Down Syndrome and Miscarriages
Type:
OtherDescription:
This analysis and discussion activity reinforces student understanding of the process of meiosis and the importance of having exactly the right number of copies of each chromosome in our body's cells. This activity also helps students to understand that miscarriages are often the result of genetic abnormalities and that genetic conditions sometimes are not inherited (e.g. Down syndrome due to meiotic nondisjunction). Optional additional questions can be used to promote student understanding of sex chromosome abnormalities and X chromosome inactivation.
