Definitions:

Sister Chromosomes

Identically replicated chromosomes, paired and connected by a centromere, originating from the same chromosome during cell division.

Metaphase Plate

An imaginary plane perpendicular to the spindle fibers of a dividing cell, along which chromosomes align during metaphase.

Meiosis

A type of cell division that reduces the chromosome number by half, resulting in the production of four haploid cells, crucial for sexual reproduction.

Diploid Chromosome Number
