three or more alleles for a particular gene/trait
A non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes; an additive effect of two or more genes on a single phenotype like skin color or height
A property in which genes have multiple phenotypic effects
when phenotypes of the heterozygote and dominant homozygote are identical
when the phenotype of F1 hybrids is somewhere between the phenotypes of the two parental varieties
when two dominant alleles affect the phenotype in separate, distinguishable ways
What is the difference between Pleiotropy and Polygenic Inheritance?
Pleiotropy: One gene causes many phenotypic effects Polygenic Inheritance: Many genes affect a singular trait
Phenotypic expression of a gene at one locus alters that of a gene at a second locus. Ex: Coat color for labrador retrievers
Cystic fibrosis and sickle cell disease are examples of ______
Pleiotropy because these diseases have multiple symptoms.
What is the most basic difference between incomplete dominance and epistasis?
In incomplete dominance, two different alleles have a genetic relationship while epistasis is the genetic relationship between two genes.
