| 2138971412 | The chromosome theory of inheritance | Mendelian genes have specific loci along chromosomes, and it is the chromosomes that undergo segregation and independent assortment. | 0 | |
| 2138971413 | Wild type | The phenotype for a character most commonly observed in natural populations. | 1 | |
| 2138971414 | Sex-linked gene | A gene located on either sex chromosome. Specifically X-linked and Y-linked genes. | 2 | |
| 2138971415 | Barr body | The condensed and inactive second X chromosome found in the autosomes of females. | 3 | |
| 2138971416 | Linked genes | Genes located near each other on the same chromosome that tend to be inherited together in genetic crosses. | 4 | |
| 2138971417 | Genetic recombination | The production of offspring with combinations of traits that differ from those found in either P generation parent. | 5 | |
| 2138971418 | Recombinant types | An offspring whose phenotype differs from that of the true-breeding P generation parents. | 6 | |
| 2138971419 | Linkage map | A genetic map based on recombination frequencies that shows the relative location of genes on a chromosome. | 7 | |
| 2138971420 | Map units | The units used to express the distances between genes, where one unit is equivalent to a 1% recombination frequency. | 8 | |
| 2138971421 | Aneuploidy | An condition in which a zygote will have an abnormal number of a particular chromosome. | 9 | |
| 2138971422 | Polyploidy | A condition in which an organism will have more than two complete chromosome sets in all somatic cells. | 10 | |
| 2138971423 | Deletion | An alternation of chromosome structure where a chromosomal fragment is lost. | 11 | |
| 2138971424 | Duplication | An alternation of chromosome structure where a chromosomal fragment is attached as an extra segment to a sister chromatid. | 12 | |
| 2138971425 | Inversion | An alternation of chromosome structure where a chromosomal fragment reattaches to the original chromosome is reverse orientation. | 13 | |
| 2138971426 | Translocation | An alternation of chromosome structure where a chromosomal fragment is attached as an extra segment to a nonhomologous chromosome. | 14 | |
| 2138971427 | Genomic imprinting | Variation in phenotype depending on whether an allele is inherited from a female or male parent. | 15 |
