- law of segragation
- first law; states that the two alleles for a character segragate when gametes are formed
- alleles
- different versions of a gene
- true breeding
- all the offspring would display only one form of the character
- F2 generation
- "second filial" generation; offspring of the F1 generation
- P generation
- firsts two individuals that are crossed in a breeding experiment
- pedigree
- family history that shows how a trait is inherited over several generation
- polygenic inheritance
- when several genes influence a character
- law of independent assortment
- states that the alleles of different genes seperate independently of one another during gamete formation
- test cross
- and individual whose phenotype is dominant, but whose genotype is not known, is crossed with a homozygous recessive individual
- sex-limited genes
- located only on the X or Y chromosome
- genotype
- set of alleles that an individual have for a character
- condominance
- both forms of the character are displayed
- dominant
- expressed form of the character
- F1 generation
- "filial" generation; offspring of P generation
- recessive
- trait that was not expressed
- multiple alleles
- genes with three or more alleles
- monohybrid cross
- cross that involves one pair of contrasting traits
- incomplete dominance
- when an individual displays a phenotype that is intermediate between two parents
- phenotype
- physical appearance of a character
