|
|
|
They are more likely to evolve into a new species than other cats due to gene flow.
|
|
|
They are likely to go extinct because they have so little variation.
|
|
|
They likely underwent a bottleneck in their history.
|
|
|
The founder’s effect made it so they have several different subspecies.
|
|
|
Cheetahs never prosper and winners never cheat.
|
Detailed explanation-1: -In this bottleneck the cheetahs of North America and Europe went extinct, leaving extant only the species’ Asian and African populations. As large mammals died out across the world, the number of surviving cheetahs dwindled, which caused extreme inbreeding.
Detailed explanation-2: -Cheetahs are virtual clones, with only one to 10 percent of the genetic variability found in other feline species [source: Begley].
Detailed explanation-3: -The complete cheetah mtDNA genome has 17, 047 bp (Burger et al., 2004) and has 91% similarity with the mtDNA genome of the domestic cat (Lopez et al., 1996).
Detailed explanation-4: -Cheetah genomes are on average 95 % homozygous compared to the genomes of the outbred domestic cat (24.08 % homozygous), Virunga Mountain Gorilla (78.12 %), inbred Abyssinian cat (62.63 %), Tasmanian devil, domestic dog and other mammalian species.
