Module 6: Lesson 7 Assignment—Labs

 

Can eating sweets or salty foods determine if a pregnant couple will have a boy or a girl? Despite some persistent folk tales, there is nothing a person can do while pregnant that will influence the gender of their child. However, this is not the case with other species. In this exploration, you will determine if a change in temperature will have an effect on the gender of hatching chickens or geckos. You will see how environment can affect the expression of genes already present in the developing embryos.

 

Complete this gizmo on the effect of temperature on gender and all related activities. You will be prompted to complete your Module 6: Lesson 7 Assignment as part of the lab.
