| 8948530969 | Character | A heritable feature that varies among individuals |  | 0 |
| 8948530970 | Trait | Each variant for a character |  | 1 |
| 8948530971 | True-breeding | Over many generations, it had produced only the same variety as the parent |  | 2 |
| 8948530972 | Hybridization | Mating of two true-breeding parents |  | 3 |
| 8948530973 | Allele | Alternative versions of a gene |  | 4 |
| 8948530974 | Law of Segregation | States that the two alleles for a heritable character separate from each other during gamete formation and end up in different gametes |  | 5 |
| 8948530975 | Phenotype | An organisms appearance or observable traits |  | 6 |
| 8948530976 | Genotype | An organisms genetic makeup |  | 7 |
| 8948530977 | Testcross | Breeding an organism of unknown genotype with a recessive homozygote |  | 8 |
| 8948530978 | Monohybrid Cross | Cross of two heterozygotes(Rr) |  | 9 |
| 8948530979 | Dihybrid Cross | A cross between two individuals, concentrating on two definable traits |  | 10 |
| 8948530980 | Law of Independent Assortment | States that each pair of alleles segregates independently of each other pair of alleles during gamete formation |  | 11 |
| 8948530981 | Multiplication Rule | States that to determine the probability, we multiple the probability of one event by the probability of the other event |  | 12 |
| 8948530982 | Addition Rule | States that the probability that any one of two or more mutually exclusive events will occur is calculated by adding their individual probabilities |  | 13 |
| 8948530983 | Complete dominance | The offspring always looked like one of the two parental variety because one allele in the pair showed __________ |  | 14 |
| 8948530984 | Incomplete dominance | Three or more potential varieties from crossing tow parents |  | 15 |
| 8948530985 | Co-dominance | Two alleles each affect the phenotype in separate, distinguishable ways |  | 16 |
| 8948530986 | Pleiotropy | Most genes have multiple phenotypic effects called... |  | 17 |
| 8948530987 | Epistasis | the phenotypic expression of a gene a one locus alters that of a gene at a second locus |  | 18 |
| 8948530988 | Polygenic Inheritance | An additive effect of two or more genes on a single phenotypic character |  | 19 |
| 8948530989 | Carrier | Heterozygous person can transmit the recessive allele to their offspring without themselves having the trait |  | 20 |
