What to Focus On
- Heredity is the passing of traits from parents to offspring.
- Variation refers to differences among individuals of the same species.
- Variations arise due to mutation, segregation, and recombination.
- Mendel used pea plants for his experiments due to their clear traits and ease of cultivation.
- He studied seven contrasting traits in pea plants.
- Monohybrid cross involves one pair of contrasting traits; dihybrid cross involves two pairs.
- Gene: Unit of heredity; segment of DNA.
- Allele: Alternative form of a gene.
- Genotype: Genetic constitution (e.g., TT, Tt).
Common Mistakes to Avoid
Dominant traits are always more common in a population.
Incomplete dominance and codominance are the same thing.
Genotype and phenotype are interchangeable terms.
