Final answer:
The correct inheritance pattern for the genotype combinations BB, BW, WBW, WW is Codominance, where both alleles are expressed equally in the phenotype. Codominance can be observed in human blood groups like the MN and ABO systems.
Step-by-step explanation:
The inheritance pattern represented by the genotype combinations BB, BW, WBW, WW is Codominance. In codominance, both alleles for a given trait are expressed equally in the phenotype of the heterozygote. This is evident, for example, in the MN blood groups of humans, where both M and N alleles are equally expressed. Another example is the ABO blood group system, where individuals with genotype IAIB exhibit both A and B antigens on their red blood cells due to codominance. Similarly, in inheritance patterns where offspring display traits that are a mixture of the parental phenotypes, such as gray offspring from black and white true-breeding mice, this result is indicative of codominance. In this scenario, Codominance and multiple alleles play a role in the diversity of possible offspring.
