In mammals, a variety of genes affect coat color. One of these is a gene with mutant alleles that results in the complete loss of pigment, or albinism. Another controls the type of dark pigment with alleles the lead to black or brown colors. The albinistic trait is recessive, and black is dominant to brown. Two black mice are crossed and yield 9 black: 4 albino: 3 brown. How would you explain these results?

E) Elephants help other populations survive by repelling many large African predators

Explanation:

Elephants are large mammals. Elephants in Africa have a height of 4 meters and weigh up to 7 tons.

The role of elephants in the ecosystem is very important especially its impact both directly and indirectly on the environment. With a large size and height, other predatory animals such as lions, tigers, coyotes, hyenas do not want to get close to elephants. Elephants are animals that prefer to group. While still breastfeeding will be very protected by the mother for up to 3 years. Elephants have an average age of up to 70 years. Perhaps very few elephants have fallen prey to predators. Thus elephants are animals that indirectly protect other animals in Africa. Things like this also indirectly make grasslands become more fertile and other animal species also become more numerous.

So the most appropriate answer is E. E) Elephants help other populations survive by repelling many large African predators
