In this problem, it tells you what the genes are and what the alleles are. Are you comfortable with those words and what they mean in context of the prob?

anonymous · Answer

no what are alleles??

blues · Answer

You have a gene. A gene is a piece of information about what sort of trait the organism (in this case guinea pigs) will have. Think of it like a message. An allele is a variant or possibility for what that info actually is.

So if a gene were an email, then the allele would be the actual text inside the email. Hope that's helpful.
