A | B |
Gregor Mendel | Father of Modern Genetics |
Pea Plant | Mendel's organism of choice |
Pure Breeding | Always produce offspring like themselves |
P | Parental Generation |
F1 | First Fillial Generation |
F2 | Second Fillial Generation |
Principle of Dominance and Recessiveness | One "factor" will mask the other |
Principle of Segregation | At gamete formation, the two "factors" for a trait segregate from each other |
Molecular Genetics | The study of the structure and function of chromosomes and genes |
Alleles | Contrasting forms of a gene |
Monohybrid Cross | involves the inheritance of only one trait |
Capital letters | dominant traits |
Lowercase letters | recessive traits |
Principle of Independent Assortment | "factors" for different traits are distributed to the gametes independent of one another |
Test Cross | Unknown genotype individual crossed with a homozygous recessive |
Incomplete Dominance | when two or more alleles influence a trait resulting in an intermediate trait |
Codominance | Both alleles are expressed equally, no blending |
Heredity | The transmission of traits from parents to offspring |
Pure breeding | Produced by self-pollination |
To work genetics problems | Make a key of the trait |
