| allele | a variation of a gene’s nucleotide sequence, an alternative form of a gene |
| anther | the microsporangium of an angiosperm in which pollen grains are produced |
| cross-pollination | a reproductvie process in which pollen from one plant is transferred to the stigma of another plant |
| dominant | referring to an allele that masks the presence of another allele for the same characteristic |
| F1 generation | the offspring of cross-pollinated P1 generation plants |
| F2 generation | the offspring of self-pollinated F1 generation plants |
| genetics | the scientific study of inheritance |
| heredity | the transmission of traits from parents to their offspring |
| law of independent assortment | law stating tha tpairs of genes separate independently of one another in meiosis |
| law of segregation | law stating that pairs of genes separate in meiosis and each gamete receives one gene of a pair |
| molecular genetics | the study of the structure and function of chromosomes and genes |
| P1 generation | a strain obtained through self-pollination |
| pollination | the transfer of pollen from an anther to a stigma of a flower of the same species |
| pure | a true breeding strain that always produces offspring with a specific trait |
| recessive inheritance | a pattern of inheritance in which the phenotypic effect of one allele is only expressed within a homozygous genotype. In a heterozygous condition with a dominant allele, it is not expressed in the phenotype |
| self-pollination | pollination involving the same flower, flowers onthe same plant, or two genetically identical plants |
| stigma | an expanded apex of a pistil, supported by the style; the part of the pistil that receives pollen |
| trait | in genetics, a category within which alternate characteristics, such as height and eye color, can be observed |
| selective breeding | the process of breeding organisms that results in offspring with desired genetic traits |
| strain | pure for a trait; having two copies of the same allele; either homozygous dominant or homozygous recessive |
