Part a: interphase

just before meiosis begins, the chromosomes are replicated.

1. use ten beads and a centromere of one color to construct the long

chromosome. use ten beads and a centromere of a second color to construct

the second chromosome in the long pair. make a drawing of the

chromosomes in the space below.

2. for the second pair of chromosomes, use only five beads.

Just before meiosis begins, the cell is in interphase in which chromosomes are replicated

Explanation:

In the attached picture small beads and centromere are drawn that represent the genes joined together to form the chromosome strand. In interphase, these two chromosomal strands (represent in 2 different colors; blue and pink) are ready to replicate and end up with an identical twin called sister chromatids.
