Some Maths

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?

She's not not getting the math. She's not getting something else, at a meta level. A light needs to go on.

Can't argue with the logic, at least.

That's what makes it funny. Baldrick's not wrong, he's just wrong.
