Mating of a female rabbit with a long tongue with a male rabbit that had a short tongue resulted in 12 offspring. Two had long tongues, two had short tongues,and eight had medium-length tongues. Which allele combinations explains the tongue lengths of the offspring?
A)Short tongue dominant; long tongue recessive
B)Short tongue recessive; long tongue dominant
C)Short tongue dominant; long tongue dominant
D)Short tongue dominant; long tongue X-linked recessive

The pattern demonstrates codominant inheritance in which both alleles are expressed equally. The phenotype accurately expresses the genotype. Short tongues must have two short gene alleles (homozygous), medium-length tongues must have one short-tongue gene allele and one long-tongue gene allele (heterozygous), and long tongues must have two long-tongue gene alleles (homozygous).
