Ch. 9 Biology Vocab

Field of biology devoted to understanding how characteristics are transmitted from parents to offspring

Transmission of characteristics from parents to offspring

Genetically determined variant of a characteristic

Trait always produce offspring with that trait when they self-pollinate

Dominates the factor for the other trait in the pair

No observable effect on an organism's appearance when that trait was paired with a trait controlled by a dominant factor

States that a pair of factors is segregated, or separated, during the formation of gametes

Factors separate independently of one another during the formation of gametes

Two or more alternative forms of a gene

Organism's genetic makeup

Organism's appearance

When both alleles of a pair are alike

When the two alleles in the pair are different

One allele is completely dominant over another

Phenotype of a heterozygote is intermediate between the phenotypes determined by the dominant and recessive traits
