The Inheritance of Complex Traits

The Inheritance of Complex Traits. Chapter 5. Differences Among Brothers and Sisters is Due to both Genetic and Environmental Factors. 5.1 Some Traits Are Controlled by Two or More Genes. Many phenotypes are influenced by many gene pairs as well as the environment

Variation

Variation. 9.1 Phenotypic variation caused by genetic differences and by the environment. Genetic variation is the foundation of evolution Understanding the process of evolution requires understanding of the origin and transmutation of genetic variation Phenotype, genotype, locus, allele

POSTULATES FOR EVOLUTION VIA NATURAL SELECTION

POSTULATES FOR EVOLUTION VIA NATURAL SELECTION. 1 . Phenotypic variation is present among individuals in the population. 2. At least some of this phenotypic variation is due to underlying genetic variation; i.e., it is heritable.

Evolution by Natural Selection as a Syllogism

Evolution by Natural Selection as a Syllogism. If individuals in a population vary with respect to a particular trait that has some genetic basis AND 2. If the variants differ with respect to their abilities to survive and reproduce in the present environment THEN

10.3 Polygenic Inheritance. HL Material. Polygenic Inheritance. Concerns a single characteristic that is controlled by more than one gene Each allele only contributes a small amount to the overall phenotype of the individual The more genes involved, the more variation

1) heritability

1) heritability. A) is the proportion of genetic variation that is due to phenotypic variation B) is a property of an individual, not a population C) means that the trait is genetically based D) can be measured from the resemblance among relatives E) all of the above.
