On the planet CCR, there is a recessive condition known as
Jambalaya. People with this trait have an uncontrollable
urge to Rock-n-Roll. The two alleles at the trait locus are
labeled R (trait) and r (wild type).



Problem 1. If the probability of transmitting an r allele is 0.44,
then what is the probability that any child born to carrier
parents will be affected (i.e., will rock!)?


Is this the same thing as probability of finding (RR)? if so would it be
P (RR) = 0.56 * 0.56 = .31


wild type means normal correct? (not have the disease) so that would be Rr or rr?
I know that recessive alleles are normally shown by two small letters but in this case it is not?

thanks.
 
Your math/solution look right to me.

Wild-type is normal, in this case represented by r, so once again you are right: rr and Rr would be normal phenotype. You are also correct that recessive alleles are typically indicated by lowercase and dominant alleles in uppercase, but that doesn't appear to be the case here.
