| Scientific study of heredity | ||
| A haploid egg or sperm cell; gametes unite during sexual reproduction to produce a diploid zygote. | ||
| A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses). | ||
| The genetic makeup of an organism. | ||
| Diagram showing the relative locations of each known gene ona particular chromosome | ||
| The union of haploid gametes to produce a diploid zygote. | ||
| Term used to describe organisms that produce offspring identical to themselves if allowed to self-pollinate | ||
| Specific characteristics that varies from one individual to another | ||
| (1) Offspring of two parents that differ in one or more inheritable characteristics. (2) Offspring of two different varieties or of two different species. | ||
| An alternative form of a gene. | ||
| Separation of alleles during gamete formation | ||
| Likelikhood that a particular event will occur | ||
| The checkerboard diagram used for analysis of allele segregation. | ||
| Having two identical alleles for a given trait. | ||
| Having two different alleles for a given genetic character. | ||
| The physical and physiological traits of an organism. | ||
| Independent segregation of genes during the formation of gametes | ||
| A type of inheritance in which F1 hybrids have an appearance that is intermediate between the phenotypes of the parental varieties. | ||
| A phenotypic situation in which both alleles are expressed in the heterozygote. | ||
| Three or more alleles of the same gene | ||
| Traits controlled by two or more genes | ||
| Term used to refer to chromosomes that each have a corresponding chromosome from the opposite-sex parent | ||
| Term used to refer to a cell that contains both sets of homologous chromosomes | ||
| Structure containing 4 chromatids that forms during meiosis | ||
| Process by which the number of chromosomes per cell is cut in half through the separation of homologous chromosomes in a diploid cell | ||
| Term used to refer to a cell that contains only a single set of chromosomes and therefore only a single set of genes. | ||
| Process in which homologous chromosomes exchange portions of their chromatids during meiosis |
