3. A diploid cell has two pairs of homologous chromosomes. How many different combinations of chromosomes could there be in the gametes?

Answer 4

You're right; they DO have to match completely.

Toward the beginning of Meiosis, the chromosomes need to duplicate themselves.

Here's a picture of a duplicated chromosome:

You can see here that the YELLOW chromosome has made a copy of itself.
The BLUE chromosome is completely identical to the yellow one.

So, they are both definitely identical in SIZE and LENGTH.

That is why you have to use the same number of beads.
Both chromosomes must be equal in size.
