SDC 3.1 Human Genetics

What is the primary focus of evolutionary psychology?

• How individual differences arise through gene-environment interaction

• Universal patterns of behavior and cognitive processes evolved over time

• The role of chromosomes in genetic variation

• The study of genetic mutations and their effects

What is the genotype of an individual?

• The physical traits inherited from parents

• The observable characteristics of an individual

• The genetic makeup of an individual

• The environmental influences on an individual

Which of the following is a recessive genetic disorder?

• Sickle-cell anemia

• Skin color

• Cleft chin

• Height

What is the role of alleles in genetics?

• They are the observable traits of an individual

• They are specific versions of a gene

• They are the dominant traits in a population

• They are the environmental factors affecting genes

What does the concept of 'range of reaction' suggest?

• Genes solely determine an individual's potential

• Environment sets limits on potential, and genes determine achievement

• Genes set limits on potential, and environment determines achievement

• Genes and environment have no interaction

What is the significance of genetic variation?

• It prevents any environmental influence on genes

• It contributes to a species' adaptation to its environment

• It ensures identical traits in a population

• It eliminates harmful mutations

What is the primary benefit of the sickle-cell gene in certain environments?

• It provides immunity to all diseases

• It offers protection against malaria

• It enhances physical strength

• It increases lifespan

What is the focus of behavioral genetics?

• The study of genetic mutations

• Universal patterns of behavior over time

• How individual differences arise through gene-environment interaction

• The role of chromosomes in genetic variation

What is a Punnett square used for?

• Analyzing the DNA sequence of an individual

• Measuring the physical traits of an individual

• Determining the environmental influences on genes

• Predicting how genes will interact in the production of offspring

What does epigenetics study?

• The role of chromosomes in genetic variation

• The fixed and limited nature of genotypes

• How the same genotype can lead to different phenotypes

• The universal patterns of behavior over time
