Heterozygous male guinea pigs with black, rough hair (bbrr) are crossed with heterozygous female guinea pigs with black, rough hair (bbrr). the incomplete punnett square below shows the expected results form the cross

The diagram shows the results when two parents are crossed. the letters represent alleles for a trait that is controlled by three different genes. which best describes this inheritance pattern? multiple allele because a trait is controlled by three different genes polygenic because the offspring have alleles from both parents multiple allele because the offspring have alleles from both parents polygenic because a trait is controlled by three different genes
