In zoos, lions and tigers mate and produce viable hybrid offspring called tigons or ligers. Hybrids were never recorded in Asia, however, where their ranges once overlapped. All of the following lines of evidence can be used to determine relatedness among organisms except a. similar amino acid sequences in proteins. A biologist discovers two new species of organisms, one in Africa and one in South America, and they resemble each other closely. The amino acid sequence of five other species is determined.
