Of all the animals in the animal kingdom which one(s) would have the best chance for survival in mountains?
Fittoniya [83]

Answer & explanation:

Mountains are large formations of land at high altitudes, where conditions are often difficult. For example, cold weather and food shortages.

In the highest areas of the mountains, animals such as vultures, eagles, hawks and other birds of prey usually prevail.

In addition, it is common for the sides of the mountains to be covered with forests. In these areas it is possible to observe the predominance of animals such as moose, goats, sheep, skunks, llamas and lynx. This group has good climbing skills and manages to stay in the side of the mountains and in some high areas (not as high as the previous group).

Meanwhile, in the lower parts of the mountains, where the forest is denser, it is possible to observe the predominance of snakes, wolves, marmots, foxes, etc.

Answer:

Genes coding for proteins involved in chiasma formation.

Explanation:

Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.

Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
