Humans have 23 pairs of chromosomes in each cell.
Chromosomes contain DNA and are the basis of heredity.
Men have one X and one Y chromosome, while women have two X chromosomes.
Gametes have 23 individual chromosomes.
Meiosis is the division of cells that forms gametes, while mitosis produces identical cells.
Chromosomes double their DNA content before division.
Mutations are rare and occur randomly, but can be passed on if they occur in reproductive cells.
Genes are portions of chromosomes that carry hereditary information, and alleles are different versions of genes.
Dominant alleles always express themselves, while recessive alleles only express themselves if present in two copies.
An individual's genotype is the set of their alleles, while their phenotype is their visible characteristics.
