CHROMOSOMES

A chromosome that is similar in physical attributes and genetic information to another chromosome with which it pairs during meiosis. A member of homologous pair of chromosomes. Key idea: Not identical to the other member of its pair.

Chromatin is the combination of DNA and proteins that make up the contents of the nucleus of a cell.

A chromatid is one copy of a duplicated chromosome, which generally is joined to the other copy by a centromere,[1] for the process of nuclear division (mitosis or meiosis)
