The MN blood group locus controls antigen expression for blood type. The LM allele expresses M antigen and LN allele expresses the N antigen. The LM and LN alleles at the MN blood group locus exhibit co-dominance. What are the expected genotypes, phenotypes and the ratios of the progeny resulting from the following cross? LMLM x LMLN 50% express the N antigen All statements are correct 100% express the M antigen 50% have LMLM and 50% have LMLN genotypes.
