How similar are rats and humans genetically
NettetRats and humans have remarkably similar biochemistry, genetics, and neuroanatomy. We are actually far, far closer to rats biologically than we are to, say, dogs or cats. … NettetIf there is more than one dominant male, the group of alpha males are usually related. Two lines are then being "line bred". Also, in some populations, such as the Crater lions, it is known that a population bottleneck has occurred. Researchers found far greater genetic heterozygosity than expected. [37]
