Document Summary
Gregor mendel and pea plants: looked at pairs of binary (contrasting) traits of the garden pea plant. In other words, each trait because homozygous (aa and aa: this means each trait appeared in one generation after another without being mixed up with the other trait. Mendel worked on one trait at a time: this means he counted thousands of seeds, pods, and plants to create a statistical method. A statistical method is very important in scienti c research: mendel followed how a hereditary factor is inherited from parental strands to offspring. Generations: p or p1 = the parental generation, f1, f2, fn = the lial generation or the offspring; subsequent generations. The yellow trait masks the green trait: yellow is dominate over green. Allele: different forms of a given gene. Genotypes are not always equal to phenotypes: we infer genotypes from phenotypes and inheritance patterns. F1 to f2 generation: once true breeding is established, allow f1 to self fertilize.
