In guinea pigs, black hair ( b) is dominant to brown hair ( b) and short hair ( h) is dominant to long hair ( h ). The punnett square works, however, only if the genes are independent of each other, which means that having a particular allele of gene a does not alter the probability of possessing an allele of gene b. In order to do this, you will also have to understand the meaning of the terms below. The larger punnett square is used for dihybrid crosses where each of the parents produces four types of gametes depending on the distribution of the alleles of the genes.
