Heredity the passing of traits from parents to offspring. | Sex-linked gene a gene that carried on x or y chromosomes. |
Trait a characteristic that an organism can pass on to its offspring. | Carrier a person who has one recessive allele for a trait but does not have the trait. |
Purebred the offspring of many generations that have the same traits. | Sex chromosome a pair of chromosomes carrying genes that determine whether a person is male or female. |
Hybrid an organism that has two different alleles for a trait | Genetic disorder an abnormal condition that a person inherits through genes or chromosomes. |
Offspring - the product of the reproductive process of an animal. A child | Pedigree a chart or family tree that tracks which members of a family have a particular trait. |
Gene the set of information that controls a trait. | Inbreeding a selectively breeding method in which two individuals with identical or similar sets of alleles are crossed. |
Alleles the different forms of a gene | Hybridization a selective breeding method in which two genetically different individuals are crossed |
Dominant an allele whose trait always shows up in the organism when it is present. | Clone an organism that is genetically identical to organism from which it was produced. |
Recessive an allele that masked when a dominant allele is present. | Genetic Engineering the transfer of a gene from the dna of one organism into another organism. |
