Evolution Answers

Differentiate between Sympartic Speciation and Geographical Speciation.

Outline the hominid lineage upto modern human and discuss the major evidences that support it.

Explain how homologous organs and

vestigial organs support speciation through

evolution.

If the original population of 200 (from question #1) was hit by a tsunami and 100 organisms were wiped out, leaving 63 homozygous recessive out of the 100 survivors. Assuming that all individuals were equally likely to be wiped out, how did the tsunami affect the predicted frequencies of the alleles in the population? (Hint: Assume the new population is at equilibrium – AFTER the event – so you are comparing two populations which are at equilibrium to look for changes in allele frequencies.)

If 15% of the population carries at least one copy of the recessive allele: What is the predicted frequency of individuals in the population that express the dominant phenotype? What is the predicted frequency of individuals in the population that express the recessive phenotype?

organisms.
