Chromosomes in a Koala

A koala is a herbivorous mammal native to Australia.They have little, tailless bodies and large head with round, fluffy ears and large nose. The koala has an average body length of 60–85 cm (24–33 in) and weighs 4–15 kg (9–33 lb). Koalas have 16 chromosomes in each cell, a set of each parent. This is similar to other mammals; they have a low chromosome number and a very stable genome arrangement, meaning genetic errors are rarer.
