WebIn biology, homology is similarity due to shared ancestry between a pair of structures or genes in different taxa.A common example of homologous structures is the forelimbs of vertebrates, where the wings of bats and birds, the arms of primates, the front flippers of whales and the forelegs of four-legged vertebrates like dogs and crocodiles are all … WebAn example of homologous characters is the four limbs of tetrapods. Birds, bats, mice, and crocodiles all have four limbs. Sharks and bony fish do not. The ancestor of tetrapods evolved four limbs, and its descendents have inherited that feature — so the presence of four limbs is a homology. red and black striped tights babyWebMolecular homology can be recognized at a variety of organizational levels, which are interdependent. For example, the recognition of homology at the site level involves a statement of homology at the sequence level, and vice versa. red and black studio randburg
