BIO 151 Final Exam

What were the two main ideas in Darwin's theory of evolution?

Individuals can evolve.

Mendel's Law that states that a sperm or egg carries only one allele for each inherited characters because allele paris are separated from each other during production of gametes:

What were the gaps that were filled in by Mendel during the Modern Synthesis?

What isn't a condition that is necessary for natural selection?

Which mechanism of evolutionary change occurs when a population gains or loses alleles when fertile individuals move into or out of a population or when genes are transferred?

Microevolution is:

What isn't a condition for the Hardy Weinberg equilibrium?

What does directional selection do to a population?

Natural Selection is limited by the fact that it has to act on genes that can be inherited.

What is necessary for an evolved organism to be considered a new species under the biological species concept?

Which reproductive isolating mechanism happens before fertilization occurs?

Which post zygotic barrier is when the interaction of parental genes impairs hybrids development of survival?

What is the first step in speciation?

Which type of speciation occurs in the same area?

When natural selection begins to favor any allele in the parental populations the form pre zygotic barriers which will result in separate species if hybrids are not fit?

Similarity in structures due to convergent evolution are called:

Correct order of Binomial Nomenclature:

What was the significance of the Cambrian Explosion?

Which animal phyla is a lophotyochzoa (grows by adding to existing body)?

Which germ layer develops the skin, hair and nervous system?
