The most recent ice age began 5,000 years ago two to three million years ago 15,000 years ago one million years ago

The correct answer would be two to three million years ago.

Explanation:

The Quaternary glaciation, also known as the Pleistocene glaciation was the most recent ice age which began about 2.6 million years. Major extinctions event of large mammals or megafauna which include mammoth, mastodons, glyptodons and others began late in this ice age.

Thus, the correct answer would be two to three million years ago.

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
