| Question |
Answer |
| Allele | alternative forms of genes |
| dominant trait | the trait that is observed |
| Heredity | passing on characteristics from parent to off-spring |
| Genetics | the study of heredity |
| Traits | characteristics inherited |
| Gametes | sex cells |
| Pollination | transfer of pollen to the pistil |
| Fertilization | male gamete in the pollen grain meets and fuses with the female gamete in the ovule |
| Hybrid | off-spring of the parent that has different form of the same trait (short / tall) |
| Recessive | trait that is not visible |
| Phenotype | visible characteristics |
| Genotype | genetic characteristics |
| Heterozygous | if the two alleles for a trait differ from one another |
| Diloid | a cell with two of each kind of chromosome (2n) |
| Haploid | a cell with one of each kind of chromosome (n) |
| Homologous chromosomes | paired chromosomes in a diploid cell |
| Meiosis | cell division that produces a gamete containing half the number of chromosomes of its parent |
| Sexual Reproduction | reproduction that involves the production and fusion of haploid cells |
| Crossing over | exchange of genetic material between nonsister chromatids from homologous chromosomes during Prophase I of meiosis |
| Genetic recombination | major sourse of genetic variation caused by reassortment or crossing over during meiosis |
| Nondisjunction | failure of homologous chromosomes to separate properly during meiosis |
