Study Notes
Classical Genetics
- Classical genetics is the branch of genetics focused on observable outcomes of reproduction.
Genotype vs. Phenotype
- Genotype: An organism's genetic makeup (e.g., BB, Bb, bb).
- Phenotype: Observable physical traits resulting from the genotype (e.g., purple flowers, white flowers).
Alleles
- An allele is a variant of a gene that controls the same trait.
- Alleles usually appear in pairs.
- Alleles can be dominant or recessive, affecting how they express.
Homozygous vs. Heterozygous
- Homozygous: Having two identical alleles for a gene (e.g., BB, bb).
- Heterozygous: Having two different alleles for a gene (e.g., Bb).
Dominant vs. Recessive
- Dominant allele: Expressed even when paired with a recessive allele, the trait will be visible.
- Recessive allele: Visible only when paired with another recessive allele; hidden by dominant traits.
