how many homologous pairs in a sex cell
Definition: Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position, and centromere location. The position of the genes on each homologous chromosome is the same, however the genes may contain different alleles. Example: A human karyotype shows the complete set of human chromosomes. Human cells contain 23 pairs of chromosomes for a total of 46. Each chromosome pair represents a set of homologous chromosomes. In males, the sex chromosomes X and Y are homologues. In females, both X chromosomes are homologues.
