Question

What fraction or percentage of the class do you expect to have

unattached earlobes? What fraction of the class do you expect to have
attached earlobes? What reasoning can you provide to support your
prediction?
Answer in 2-3 complete sentences. Use the data you recorded from
the discussion to support your prediction if available.

Answer 1

I expect that approximately half of the class will have unattached earlobes, while the other half will have attached earlobes. This is because the trait for having attached or unattached earlobes is determined by a single gene with two alleles, and these alleles are equally common in the population. Therefore, the probability of an individual having attached earlobes or unattached earlobes is roughly equal. Therefore, I would expect that about half of the class will have each type of earlobe.
