Term | Definition |
trait | a specific characteristic or feature exhibited by an organism |
true breeding | organisms that exhibit the same traits, generation after generation |
cross | the fertilization of a female gamete of specific gamete origin with a male gamete of specific origin |
P generation | in breeding, the organisms initially crossed and are typically true breeding |
F1 generation | the offspring of a cross of the P generation |
monohybrid cross | a cross of two individuals that differ by one trait |
F2 generation | the offspring of a cross between the F1 generation |
dominant | the form of a trait that always appears when an individual has an allele for it |
recessive | the form of a trait that only appears when an individual has two alleles for it |
law of segregation | traits are determined by pairs of alleles that segregate during meiosis so that each gamete receives one allele |
genotype | the combination of alleles for any given trait, or the organism's entire genetic make-up |
phenotype | the physical and physiological traits of an organism |
homozygous | an organism that has two identical alleles of a gene |
heterozygous | an organism that has two different alleles of a gene |
Punnett square | a grid used to illustrate all possible genotypes and phenotypes of offspring from genetic crosses |
test cross | a cross between a parent of unknown genotype and a homozygous recessive parent |
dihybrid cross | a cross of two individuals that differ in two traits due to two different genes |
law of independent assortment | during gamete formation, the two alleles for one gene segregate or assort independently of the alleles for other genes |
chromosome theory of inheritance | traits determined by genes are inherited through the movement of chromosomes during meiosis |
pedigree | a flowchart that uses symbols to show the inheritance patterns of traits in a family over many generations |
autosomal inheritance | the inheritance of traits determined by genes on the autosomal chromosomes |
autosomal dominant | the inheritance of a dominant phenotype whose gene is on an autosomal chromosome |
autosomal recessive | the inheritance of a recessive phenotype whose gene I on an autosomal chromosome |
genetic counsellor | a health-care professional with specialized training in medical genetics and counselling |
gene therapy | a technique aimed at treating genetic disorders by introducing the correct form of the defective gene into a patient's genome |
