10 gru 2015 · Here we present a detailed annotation and analysis of the assembled whole-genome sequence of African cheetah that affirms the genome-wide reduction of cheetah diversity and identifies gene adaptations that occurred in the cheetah’s evolutionary lineage.
20 maj 2017 · With the example of the cheetah, the conservation community began to pay attention to genetic loss in small threatened populations. The early studies of cheetahs made these points so persuasively that they were repeated in the popular media and many readers simply presumed that cheetahs were doomed.
Genetic drift is the reason why we worry about African cheetahs and other species that have small population sizes. Why does it really matter if a species has low or high levels of genetic...
1 sie 2016 · Heterozygosity has declined among wild Namibian cheetahs over the last 30 years. •. Intensive genetic management has minimized further inbreeding in captive cheetahs. •. Heterozygosity did not correlate with semen quality in either population. •. Genetic diversity was lower in proven versus unproven breeders housed in captivity. Abstract.
Two-dimensional gel electrophoresis of 155 abundant soluble proteins from cheetah fibroblasts also revealed a low frequency of polymorphism (average heterozygosity, 0.013). Both estimates are dramatically lower than levels of variation reported in other cats and mammals in general.
18 kwi 2023 · Asiatic cheetah is a critically endangered mammal with large home range that suffered from extreme range reduction and population decline. Their population is now fragmented into two subpopulations. We used genetic markers to estimate genetic diversity, relatedness, minimum effective population size and gene flow, and to assess population ...
1 sie 2016 · Using 12 microsatellite markers, we evaluated the relationship between heterozygosity and reproductive traits among wild (n = 54) and captive (n = 43) male cheetahs born from 1976–2007.
