| Question | Answer |
|---|---|
| Autosome | In humans, chromosomes 1-22. Matching pairs of chromosomes. |
| carrier | A heterozygous individual who appears normal, but genotypically possesses a recessive gene for a potentially harmful gene. |
| codominant alleles | Equal expression causes the phenotypes of both homozygous parent organisms to be produced in the heterozygous offspring. |
| hybrid | Offspring produced when two varieties or closely related individuals are mated;often done to increase size or vigor. |
| inbreeding | Mating between closely related individuals to produce pure results;however it sometimes can have undesirable results. |
| incomplete dominance | the inheritance pattern in which the phenotype of the heterozygote is intermediate to the two homozygous parents. Neither allele is strong enough to mask the other, so they combine. |
| multiple alleles | Some organisms such as flowers or rabbits can come in many different colors.The genetic trait for color is said to have this. |
| pedigree | A family tree; A graphic representation showing patterns of inheritance in a family or breeding group. |
| polygenic inheritance | A trait such as skin color which is affected by the combination of several different genes. |
| sex chromosome | In humans, Chromosome pair 23.;XX or XY |
| sex-linked trait | An inherited characteristic, such as color blindness, controlled by genes located on chromosomes 23. |
| testcross | A breeding technique used to determine if an individual is homozygous dominant or heterozygous for a particular trait. |
