What to Focus On
- Heredity is the passing of traits from parents to offspring.
- Variation refers to differences among individuals of the same species.
- Mutations and genetic recombination are the main sources of variation.
- Mendel used garden pea (Pisum sativum) for his experiments.
- Pea plants have clear contrasting traits and allow controlled pollination.
- He studied seven pairs of contrasting characters over generations.
- Monohybrid cross studies one pair of contrasting traits.
- F1 generation shows only the dominant trait.
- F2 generation shows a 3:1 phenotypic ratio and 1:2:1 genotypic ratio.
Common Mistakes to Avoid
Dominant traits are always more common in a population.
Phenotypic ratio is the same as genotypic ratio in monohybrid cross.
Mendel’s laws apply to all genes in all organisms equally.
