The length of time of gestation varies among animals, but is very similar among the great apes: human gestation is 266 days, while chimpanzee gestation is 237 days, a gorilla’s is 257 days, and orangutan gestation is 260 days long. The fox has a 57-day gestation. Dogs and cats have similar gestations averaging 60 days.

Somatic mutations, occurring in non-reproductive cells like liver cells, are not inherited and die with the individual. In contrast, germline mutations in sperm and eggs can be passed to future generations, making them significant in genetic inheritance. Understanding this distinction is crucial for comprehending how genetic information is transmitted across generations.
