What type of twins are formed when two eggs (ova) are fertilized by two sperm and produce two genetically unique children?
Fraternal or dizygotic twins
What type of twins are formed when one fertilized egg (ovum) splits and develops into two babies with exactly the same genetic information?
Identical or monozygotic twins
Which of the following is an example of an environmental influence on development?
A person with poor diet and poor medical care during pregnancy may affect a fetus' brain development.
Which of the following is an example of hereditary influence on development?
A child has weak muscles as a result of muscular dystrophy and one of his parents has the same problem.
Which field of study focuses on functional explanations of how behaviors evolved?
Evolutionary psychology
What is the process by which organisms with desired traits are chosen to be parents of the next generation?
Artificial selection
Why is experimentation with animals considered critical in medical research?
To progress towards treating or preventing serious conditions like AIDS and Alzheimer's disease.
What ethical issue arises when considering animal experimentation in comparison to human research?
The question of whether animal research is acceptable under any circumstances.
Which aspect makes animal research easier for understanding mechanisms of behavior?
Observing animal behavior in natural settings.
What is a key reason why some procedures that are unethical with humans are conducted on animals?
To gain important knowledge that might be illegal or unethical to obtain with humans.
How does animal research contribute to progress in medicine and biological psychology?
By allowing research that would be slow or impossible without animals.
In what way has animal research impacted the development of medical treatments?
By providing methods for preventing or treating conditions like polio and AIDS.
Which of the following best describes a functional explanation in evolutionary biology?
It explains why a particular trait was advantageous and favored by natural selection.
What is the difference between homozygous and heterozygous conditions for a gene?
Homozygous means having an identical pair of genes, while heterozygous means having a different pair of genes.
What is the primary difference between dominant and recessive genes?
Dominant genes show a strong effect in both homozygous and heterozygous conditions, while recessive genes show their effect only in the homozygous condition.
Which of the following statements about Gregor Mendel's contributions to genetics is correct?
He demonstrated that inheritance occurs through genes, units of heredity that maintain their structural identity from one generation to another.
Which of the following best describes autosomal genes?
They are genes responsible for inherited traits that are not linked to sex.
What is the primary difference between the X and Y chromosomes in terms of their gene content?
The X chromosome contains genes for approximately 1500 proteins, while the Y chromosome contains genes for only 27 proteins.
Test your knowledge on genetic variation, recombination, mutation, and evolutionary psychology. Explore concepts related to sex-limited traits, recombination creating new gene combinations, rare mutations, and functional explanations of behavior evolution.
