what does it mean to be genetically polymorphic? to have different forms of individuals as a result of discontinuous genetic variation ex: when more than one allele occupies that gene's locus within a population (hair color) What kind of traits did Mendel observe? simple, distinctive phenotypic traits that are determined by single genes (monogenic and qualitative) Quantitative traits are ________________ polygenic what does it mean for a trait to be polygenic? The expression of the trai...

Eugenics - ️️The science of improving a human population by controlled breeding to increase the occurrence of desirable heritable characteristics. Developed largely by Francis Galton as a method of improving the human race, it fell into disfavor only after the perversion of its doctrines by the Nazis. Genomic imprinting - ️️Phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced...
