| Question | Answer |
|---|---|
| Heredity | Process by which offspring inherit traits from their parents |
| Genetics | Study of heredity |
| Stamen | Includes the anther and filament and are the male reproductive organs |
| Pistil | Including the stigma, style, and ovary are the female reproductive organs |
| Self pollination | A reproductive process by which the pollen grains from an anther transfer to a stigma of the same plannt |
| Cross pollination | A reproductive process by which the pollen grains of an anther transfer to the stigma of an entirely different plant |
| P generation | The parental generation, the first two individuals that mate in a genetic cross |
| F1 generation | The first generation, offspring of P generation |
| F2 generation | The second filial generation |
| Allele | One of the alternate forms of a gene that governs a characteristic (like eye color) |
| Dominant | The allele that is fully expressed |
| Recessive | A trait that doesn't appear in the F1 generation and but reappears in the F2 generation |
| Trait | A genetically determined variant of a characteristic |
| Homozygous | An individual who has identical alleles for a trait |
| Heterozygous | An individual that has two different alleles for a trait |
| Genotype | The pair(s) of genes for a trait |
| Phenotype | The organism's appearance mach due to genotype |
| Law of segregation | Mendel's law that states that two pairs of homologous chromosomes separate in meiosis so that only one chromosome from each pair is present in a gamete |
| Law of independent assortment | the law that states that genes separate independently of another in meiosis |
| Punnett square | (a graphic to represent the results of a cross) |
| Test Cross | a test cross is used to determine if an individual exhibiting a dominant trait is homozygous or heterozygous for that trait. |
| Incomplete dominance | A heterozygous condition in which both alleles at a gene locus are partially expressed, often producing an intermediate phenotype. |
| Codominance | A condition in which both alleles of a gene pair in a heterozygote are fully expressed, with neither one being dominant or recessive to the other |
| Probability | The likelihood that a given event will occur |
| 22/24 | Define second filial generation. Redo definition of recessive. Definition missing for Punnett square. Explain test cross better. |
