Instructions: Q.1, 2 6 are compulsory.
Answer any two questions from Q.3, 4 5
Total Marks: 70
Q.1 Multiple choice questions (per question 2 marks) 14
The effect of natural selection may be countered by
gene flow genetic drift
mutation inbreeding
Mating with relatives is called
inbreeding outcrossing
random mating clines
Which of the following conditions can result in evolution in a population?
Natural selection is not
occurring
Mutation is not occurring
All mating is totally random None of the above
Slight genetic change over a few generations in a population that does not
result in the evolution of a new species is:
microevolution macroevolution
evolutionary equilibrium genetic drift
Anagenesis is
the evolution of new species within a single evolutionary line without
branching
developing a special adaptation for survival
Species distribution
questioning or testing of hypotheses
A small, isolated population is more likely to undergo speciation than a large
population because of a small population
is more effected by genetic drift and natural selection
contains relatively more genetic diversity
is more susceptible to gene flow
has a higher mutation rate
"The sun total of the genetically inherited changes in the individuals who are
members of a population" is a description of
Non-random mating genetic drift
evolution natural selection
