| Question | Answer |
|---|---|
| Heredity | The passing on of physical or mental characteristics genetically from one generation to another |
| Genetics | The study of heredity and the variation of inherited characteristics |
| Stamen | The male fertilization organ of a flower that normally has a pollen containing anther and a filament |
| Pistil | The female organ of a flower that consist of a Stigma, style and, ovary |
| Self-pollination | A reproductive process in which pollen grains From an anther falls Into the stigma of the same plant |
| Cross pollination | A reproductive process in which pollen grains From an anther lands Into the stigma of another plant |
| P Generation | The first set of parents crossed in which their genotype is the basis for predicting the genotype of their offspring, which in turn, may be crossed |
| F1 Generation | The first filial generation, which is comprised of offspring(s) resulting from a cross between strains of distinct genotypes. |
| F2 Generation | The second filial generation, which is comprised of offspring(s) resulting from a cross of the members of F1 generation. |
| Allele | One of two or more alternate forms of a gene that comes from a mutation |
| Dominant trait | The trait that is dominant or most common because it over write the recessive |
| Recessive trait | The trait that is less common and only shows when there is no signs of the dominant trait |
| Trait | A distinguished quality or characteristic that is inherited by one or both of your parents |
| Homozygous | Having the same alleles at a particular gene locus on homologous chromosomes. |
| Heterozygous | Having different alleles at one or more corresponding chromosomal loci. |
| Genotype | 1. The genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms |
| Phenotype | The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. |
| Law of segregation | members of a pair of homologous chromosomes separate during the formation of gametes and are distributed to different gametes so that every gamete receives only one member of the pair |
| Law Of Independent Assortment | each member of a pair of homologous chromosomes separates independently of the members of other pairs so the results are random |
| Punnett Square | a diagram that is used to predict an outcome of a particular cross or breeding experiment |
| 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 |
| 24/24 |
