Human skin cells contain 46 chromosomes, or 23 chromosome pairs, and after mitosis, the two daughter cells also have 46 chromosomes. Mitosis is a cellular process that creates two identical daughter cells from one origin... More »

On a chromosome, genes are arranged in a linear fashion along the chromosome, but chromosomes only line up into homologous pairs during cell division. During mitosis (typical cell division), chromosomes line up through t... More »

Meiosis leads to genetic variability through genetic recombination, sometimes called crossing over, in prophase I and the chromosome arrangement in the metaphase I. Genetic variability is important for species because it... More »
