The video explores the nature vs. nurture debate, emphasizing that both genetics and environment shape traits. It explains genetic interactions, complex traits, and the role of epigenetics. The video uses examples like Labrador colors and human height to illustrate these concepts. It also discusses phenotypic plasticity in bees and the implications of heritability and social inequality. The conclusion highlights the complexity of traits and the interplay of nature and nurture.

What is epistasis?

• One gene affecting the expression of another

• A single gene controlling a trait

What percentage of height variation within a population can be explained by genetics?

• 80%

• 70%

• 60%

• 50%

What field studies how environmental factors can turn genes on or off?

• Biochemistry

• Molecular Biology

What is the role of methyl groups in gene expression?

• They duplicate the genes

• They mutate the DNA sequence

• They block genes from being read

• They enhance gene expression

What is heritability?

• The ability to inherit wealth

• The genetic contribution to individual differences

• The environmental influence on traits

• The mutation rate of genes

What is phenotypic plasticity?

• The ability of an organism to change its phenotype in response to environmental changes

• The genetic mutation of an organism

• The inheritance of traits from parents

• The fixed expression of genes

What is the main takeaway about nature and nurture?

• Neither nature nor nurture affects traits

• Nature is more important than nurture

• Both nature and nurture interact to shape traits

• Nurture is more important than nature
