Chromosome Pair

Homologous chromosomes.chromosome pair

two chromosomes of the full diploid karyotype that are similar in form and function but that usually differ in content, one normally being inherited from each parent and one being transmitted to each progeny; in the heteromorphic sex (in humans, the male), one pair, the sex chromosomes, differ markedly in appearance, content, and function.

Genetics with Mitosis and Meiosis

... cycle: G-1 S-phase G-2 M-phase (division) Mitosis: Before S-phase, each chromosome consists of one strand of DNA. The DNA is copied during S-phase. ... apart, but there are half as many chromosomes (one from each homologous pair). This one should be easy. This was actually a bit confusing for me. ...
