| 5571483591 | Monohybrid Cross | Cross between parents that differ in only one trait. | 0 | |
| 5571483592 | Locus | The physical condition of a trait or gene on a chromosome. | 1 | |
| 5571483593 | Alleles | Alternative form of a gene; occur at the same locus on homologous chromosomes. | 2 | |
| 5571483594 | Dominant Allele | Allele that exerts it's phenotypic effect in the heterozygote; it masks the expression of the recessive allele. | 3 | |
| 5571483595 | Recessive Allele | Allele that exerts it's phenotypic effect only in the homozygote; its expression is masked by the dominant allele. | 4 | |
| 5571483596 | Homozygous | Possessing two identical alleles for a particular trait. | 5 | |
| 5571483597 | Heterozygous | Possessing unlike alleles for a particular trait. | 6 | |
| 5571483598 | Genotype | Genes of an organism for a particular trait or traits; often designated by letters. | 7 | |
| 5571483599 | Phenotype | Visible expression of a genotype. | 8 | |
| 5571483600 | Dihybrid Cross | Cross between parents that differ in two traits. | 9 | |
| 5571483601 | Punnett Square | Visual representation used to calculate the expected results of simple genetic crosses. | 10 | |
| 5571483602 | Testcross | Cross between an individual with a dominant phenotype and an individual with a recessive phenotype to determine whether the dominant individual is homozygous or heterozygous. | 11 | |
| 5571483603 | Autosome | Chromosome pairs that are the same between the sexes; in humans, all but the X and Y chromosomes. | 12 | |
| 5571483604 | Law of Independent Assortment | Mendelian principle that explains how combinations of traits appear in gametes. | 13 | |
| 5571483605 | Carriers | Heterozygous individual that has no apparent abnormalities but can pass on an allele for a recessively inherited genetic disorder. | 14 | |
| 5571483606 | Multiple Alleles | Inheritance pattern in which there are more than two alleles for a particular trait; each individual has only two of all possible traits. | 15 | |
| 5571483607 | Codominance | Inheritance pattern in which both alleles of each gene are equally expressed in a heterozygote. | 16 | |
| 5571483608 | Incomplete Dominance | Inheritance pattern in which an offspring has an intermediate phenotype, as when a red-flowered plant and a white-flowered plant produce pink-flowed offspring. | 17 | |
| 5571483609 | Incomplete Penetrance | Dominant alleles that are either not always or partially expressed. | 18 | |
| 5571483610 | Pleiotropy | Inheritance pattern in which one gene affects many phenotypic characteristics of the individual. | 19 | |
| 5571483611 | Polygenic Inheritance | Pattern of inheritance in which a trait is controlled by several allelic pairs. | 20 | |
| 5571483612 | X Linked | Allele that is located on an X chromosome. | 21 | |
| 5571483613 | Hemizygous | Processing only one allele for a gene in a diploid organism; males are this for genes on the X chromosome | 22 |
