The relationship in which the dominant allele makes enough functional protein to express the complete trait, even when it occurs alone in heterozygous individuals.
Epistasis
What is another way to describe the genotype of a heterozygous individual?
(a)
The idea that explains how a gene can exist in more than two allelic forms (ex. Blood type A can be expressed by the genotype I^A I^A or I^A i)
Multiple Alleles
Codominance
Epistasis
Pleiotropy
The idea that explains how the ability of a gene can affect individuals in multiple ways. In other words, a single genotype can be the cause of more than one phenotype.
TRUE OR FALSE: Every single genotype has different phenotypic effects.
True
False
Individuals who are heterozygous for sickle cell anemia is an example of which kind of dominance relationship?
Complete Dominance
Incomplete Dominance
Codominance
Nondominant
The idea that a gene at one locus/location can have an effect on the expression of a gene at another locus.
Pleiotropy
Epistasis
Incomplete Dominance
Multiple Alleles
The idea that multiple different genes, not alleles, are needed to produce a certain phenotype, like skin color or height.
Environmental Factors
Multiple Alleles
Pleiotropy
Polygenic Inheritance
