Question

There are 3 types of polar bears: ones with thick coats, ones with thin

coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had ~2 cubs each
but due to the extreme temperatures, many mothers only have one cub left.
Identify a type of variation in the polar bears ______________________________________________________ Which variation is most favorable? _______________________________________________________ In 50 years, what will natural selection have most likely done to the polar bears? _________________________________________________________________________________

Answer 1

Type of variation- coat thickness

Most favourable- thick coats

In 50 years, due to natural selection it will result in the allele frequency of the thick coat increasing within the given population

Answer 2

the ones with thicker coats are the most favorable and due to natural selection they will grow even thicker coats
