In the Mexican Hairless breed of dogs, the hairless condition is produced by the heterozygous genotype (Hh). Normal dogs are homozygous recessive (hh). Puppies homozygous for the H allele are usually born dead, with abnormalities of the mouth and absence of external ears. If the average litter size at weaning is six in matings between hairless dogs, what would be the average expected number of hairless and normal offspring at weaning from matings between hairless and normal dogs?
4 normal dogs and 4 hairless dogs
