Okay so the definition "a mutation at any one of a number of genes can give rise to the same phenotype". I am a little confused.
Let's say we are investigating the heterogeneous trait of deafness and it is modeled by AAbb and hearing by AaBb (both dominant present). Whats confusing me is a) the mutation that the definition refers to, is it referring to a homozygous recessive condition for any one gene which will make the individual deaf (abd deafness is the phenotype that remains the same in the definition)? Or b) does it mean that a mutation can occur in each of one of the alleles of both genes but as long as one dominant is present in each, we hear (making that the phenotype that remains unchanged)?
Thank you.
