In 2010, the NCAA (a US college sports authority) required that athletes be tested for the genetic sickle cell trait. This trait is caused by being heterozygous (Ss) at a single gene that is NOT on the X-chromosome. Let's imagine that you have genotype Ss. Imagine that you (female) have two potential mates: Tom with genotype Ss, or Sam with genotype SS. Are your kids more likely to have genotype Ss if you marry Tom or Sam? (Note: DO NOT include the possibility of them getting the full sickle cell anemia disease - just the sickle cell trait. Hint: draw out the Punnett square to examine both possibilities.)
