Study Notes
- 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.
