A range of slightly different values for a trait in a population, as seen in height or eye color.
continuous variation
In genetics, the mating of two organisms.
Applies to an allele with an effect that is visible in a heterozygote even if only one copy of the allele is present in the individual.
All of the forms of genes, and the distribution of these forms, found within a species.
genetic variation
Genetic composition of an individual. For a given trait, the list of both alleles present in the individual without respect to which physical or physiological trait predominates.
The amount of variation for a trait in a population that can be explained by differences in genes among individuals.
Genotype consisting of two different alleles for a gene.
Genotype consisting of two copies of the same allele of a gene.
The separation of homologous pairs of chromosomes into gametes independently of one another during meiosis.
independent assortment
Situations with unique circumstances that allow a hypothesis test without prior intervention by researchers.
natural experiments
Physical and physiological traits of an individual.
Heritable traits influenced by many genes.
polygenic traits
Table that lists the different kinds of sperm or eggs parents can produce relative to the gene or genes in question and predicts the possible outcomes of a cross between these parents.
Punnett square
Heritable traits that have many possible values, such as height or eye color.
quantitative traits
The unpredictability of exactly which gametes will fuse during the process of sexual reproduction.
random fertilization
Applies to an allele with an effect that is not visible in a heterozygote.
Separation of pairs of alleles during the production of gametes. Results in a 50% probability that a given gamete contains one allele rather than the other.
