In guinea pigs, the allele for a rough coat (R) is dominant over the allele for a smooth coat (r). A heterozygous guinae pig (Rr) and a homozygous recessive guinea pig (rr) have a total of nine offspring. The punnett square for this cross shows a 50 percent chance that any particular offspring will have smooth coats. Explain how all nine offspring can have smooth coats.

    It would a significant deviation from chance {(1/2)^9}, but it is possible. Are r-bearing sperm faster swimmers?
