Genetics | The field of biology that studies how genes are transmitted from parent to offspring. |
Heredity | The transfer of traits from parent to offspring |
Trait | a genetically determined characteristic |
Pollination | When pollen is transferred from the anthers to the stigma |
Self-Pollination | When polisario occurs in the same plant |
Cross- Pollination | Pollination between the flowers of two plants |
True Breeding | Pure, always produce offspring with that trait |
P Generation | The breeding parents |
F1 generation | The offspring of the P generation |
F2 Generation | The second filial generation |
Dominant | A trait that masks or dominates another trait in the pair |
Recessive | The trait that is dominated and has no control over the outcome |
Law of Segregation | States that a pair of gametes is separated during the formation of gametes |
Law of Independent Assortment | State that factors separate independently during the formation of gametes |
Molecular Genetics | The study of structure and fiction of chromosomes and genes |
Allele | Each of an alternate form of a gene |
Genotype | An organisms genetic makeup |
