  1. A problem that completely stumped one of my adult Grade 11 Biology class today: if 1 in 4 progeny from a cross have the genotype SS, how many would you expect if there were 100 progeny? It took about 5 minutes of prompting, hints and directions before she got the answer. Then she could not work out the equivalent value for the 2 out of 4 with genotype Ss. Where do you start to help someone like that? Is there any hope of real progress?
