A couple decides to have children. Both have the same genotype:
they are fully heterozygous at the following loci: albino (Aa), MN
blood group (L^M L^N), and Rh factor (Rh+/Rh-). The Rh+ allele is

traits are located on different autosomes, determine the excepted
genotypic and phenotypic of their ratios in their
offspring.
