Epistasis

Epistasis

________: one gene affects another because the gene products are related.

Codominance

________: This is where both alleles are EQUALLY EXPRESSED.

Peas

________ were good because they were simple, had clear variation, a short generation time and produced many offspring.

Quantitative Characters

________: traits that are not A or B, rather they exist as a gradient.

Monohybrid

________: organisms that are heterozygous for ONE trait.

Dihybrid

________: organisms that are heterozygous for TWO traits.

Alleles

________ arise from slight differences in the nucleotide sequences at a locus.

Mendel

________ crossed for many generations and used large sample sizes.

Genotypes

What are most commonly associated with a range of phenotypes, not typically a single phenotype? Answer with a single words or term.

Inheritance patterns

________ are often more complex than predicted by simple Mendelian genetics.

Polygenic Inheritance

________: multiple genes independently affect a single trait.

Probability laws

________ govern Mendelian inheritance.

Law of Segregation

________: Two alleles from gametogenesis separate into different gametes.

Mendel

________ used the scientific approach to identify two laws of inheritance.

Mendel

________ used true- breeding parents (they produced the same trait over many generations) and controlled flower fertilization.
