41. Genetic variability may influence hedonic hyperphagia.42. Wild species have a range of genetic variability that allows some individuals to survive should a disturbance occur. 43. Although the species has a low genetic variability , it does not necessarily pose a threat to their survival. 44. "It's because of your genetic variability ," 45. Furthermore, these recent results suggest that sex can be maintained even when very little genetic variability is produced. 46. This low genetic variability was allegedly due to a population bottleneck caused by intense hunting in the 19th century. 47. Since their numbers are low there is a high risk of them losing too much genetic variability to survive. 48. The balance between the hypercapnic and hypoxic respiratory drives has genetic variability and can be modified by hypoxic training. 49. In contrast, the forest elephants have a lot of genetic variability , indicating that separate forest groups rarely wander and intermingle. 50. The study examined the tissue on the teeth of the skulls and determined the genetic variability based on DNA analysis.
