B6: Meiosis

Question 1

What is the first step of meiosis?

Answer 1

Cell duplicates it’s genetic information, forming two armed chromosomes (identical). After replication The chromosomes arrange themselves in pairs.

Question 2

What happens in the first division of meiosis?

Answer 2

the chromosome pairs line up in the centre of the cell. The pairs are then pulled apart so each new cell only has one copy of each chromosome.

Question 3

What happens in the second division of meiosis?

Answer 3

The chromosomes line up again in the centre of the cell. The arms of the chromosomes are pulled apart.

Question 4

What do you end up with at the end of meiosis?

Answer 4

Four gametes, each with only a single set of chromosomes in it. Each of the gametes is genetically different from the others because the chromosomes all get shuffled up during meiosis and each gamete only gets half of them, at random.
