 Heredity | traits or characteristics from parents to offspring through the inheritance of genes. |
| Heterozygous | Having different alleles at one or more corresponding chromosomal |
| Homozygous | Relating to a cell that has two identical allele |
| Hybird | an offspring resulting from cross-breeding |
| Law of independent | The law of independent assortment applies well to most plants and animals, but only to those genes which occur on non-homologous autosomal chromosomes. |
| Law of segregation | the principle, originated by Gregor Mendel, stating that during the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent. |
| Phenotype | The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences. |
| Pollination | The process by which plant pollen is transferred from the male reproductive organs to the female reproductive organs to form seeds. |
| Ressive | that one of a pair of alternative alleles whose effect is masked by the activity of the second when both are present in the same cell or organism. |
| Trait | a characteristic feature or quality distinguishing a particular person or thing |
| Zygote | The cell formed by the union of two gametes, especially a fertilized ovum before cleavage |
| Allele | One member of a pair or series of genes that occupy a specific position on a specific chromosome. |
| Dominant | having primary control, authority |
| Fertilization | The act or process of initiating biological reproduction by insemination or pollination |
| Genotype | The genetic makeup, as distinguished from the physical appearance, of an organism or a group of organisms |
| Gamete | A reproductive cell having the haploid number of chromosomes, especially a mature sperm or egg capable of fusing with a gamete of the opposite sex to produce the fertilized egg. |
| Genetics | The branch of biology that deals with heredity, especially the mechanisms of hereditary transmission and the variation of inherited characteristics among similar or related organisms. |
| Assortment | A collection of various kinds; a variety |
