CERTIFICATION EVALUATION TEST PAPER
QUESTIONS SOLUTIONS GRADED A PLUS
◉ What is a gene pool?
Answer: total of alleles found in all individuals of a species
◉ Which situation occurs after the development of a new allele?
Answer: The gene pool becomes more diverse.
◉ Which organisms would be the best mating pair to study
interspecies mating?
Answer: a leopard and a tiger
◉ Why would apple maggot flies be considered two separate races?
Answer: different allele frequencies
◉ Which steps show speciation in the correct order?
Answer: geographic isolation, evolutionary changes, reproductive
isolation
,◉ An island with a varied habitat containing ample food supports a
small founder population of lizards with very little competition.
What effect would this low level of competition have on evolution?
Answer: The population will increase in number and contain many
gene variants.
◉ What type of reproductive isolation is observed when two plants
require different amounts of darkness to produce flowers?
Answer: temporal isolation
◉ What produces gene flow?
Answer: mating between populations
◉ If all fruit flies have similar appearances, what evidence supports
the hypothesis that a male and female fruit fly are the same species?
Answer: production of viable offspring that also produce offspring
◉ Which example describes mechanical reproductive isolation?
Answer: Two fly species have differently shaped genitals that
prevent interspecies mating.
◉ What concept is illustrated by the California tarweed seeds
reaching the Hawaiian Islands and resulting in a new species?
Answer: the founder effect
, ◉ rapid natural selection that leads to divergence
Answer: punctualism
◉ True or false: To be considered different species, two populations
must accumulate genetic differences over a minimum of 100 years.
Answer: false
◉ True or false: Evolutionary change will occur rapidly in a founder
population with a small gene pool.
Answer: true
◉ Which scenario best describes the terms "subspecies" and "race"?
Answer: two populations of orange birds are separated by a
mountain but could still produce offspring
◉ What comparisons could be made for two populations of hyena
considered to be different subspecies?
Answer: They could produce fertile offspring together.
◉ What conclusion results when alleles among different human
groups are analyzed?
