Each gene pool contains a number of alleles for each inheritable trait. The number of times an allele occurs in a gene pool compared with the number of times other alleles f ...

Organisms at high altitude
.jpg?width=300)
Organisms can live at high altitude, either on land, or while flying. Decreased oxygen availability and decreased temperature make life at high altitude challenging. Despite these environmental conditions, many species have been successfully adapted at high altitudes. Animals have developed physiological adaptations to enhance oxygen uptake and delivery to tissues which can be used to sustain metabolism. The strategies used by animals to adapt to high altitude depend on their morphology and phylogeny.
