| 793262650 | rule of multiplication | a rule stating that the probability of a compound event is the product of the separate probabilities of the independent events | 21 | |
| 793262651 | rule of addition | a rule stating that the probability that an event can occur in two or more alternative ways is the sum of the separate probabilities of the different ways | 22 | |
| 793262652 | pedigree | a family tree representing the occurance of heritable traits in parents and offspring across a number of generations | 23 | |
| 793262653 | carriers | an individual who is heterozygous for a recessively inherited disorder and two therefore does not show symptoms of that disorder | 24 | |
| 793262654 | cystic fibrosis | a genetic disease that occurs in people with two copies of a certain recessive allele | 25 | |
| 793262655 | inbreeding | a mating of close relatives | 26 | |
| 793262656 | achondroplasia | a form of dwarfism | 27 | |
| 793262657 | Huntington's disease | a degenerative disorder of the nervous system that usually does not begin until middle age | 28 | |
| 793262658 | amniocentesis | physician carefully inserts a needle into uterus and extracts some amniotic fluid | 29 | |

| 793262662 | incomplete dominance | a type of inheritance in which the phenotype of a heterozygote (Aa) is intermediate between the phenotypes of the two types of homozygotes (AA and aa) | 33 | |
| 793262663 | ABO blood group | genetically determined classes of human blood that are based on the presence or absence of carbohydrates A and B on the surface of red blood types A, B, AB, and O | 34 | |
| 793262664 | pleiotropy | the control of more than one phenotypic characteristic by a single gene | 35 | |
| 793262665 | polygenic inheritance | the additive effect of two or more gene loci on a single phenotypic characteristic | 36 | |
| 804493066 | chromosome theory of inheritance | A basic principle in biology stating that genes are located on chromosomes and that the behavior of chromosomes during meiosis accounts for inheritance patterns. | 37 | |
| 804493067 | linked genes | Genes located on the same chromosome that tend to be inherited together | 38 | |
| 804493068 | recombination frequency | With respect to two given genes, the number of recombinant progeny from a mating divided by the total number of progeny. Recombinant progeny carry combinations of alleles different from those in either of the parents as a result of independent assortment of chromosomes or crossing over. | 39 | |
