LAB 4: POPULATION GENETICS &
HARDY-WEINBERG THEOREM. EXAM
QUESTIONS AND ANSWERS (VERIFIED
AND UPDATED)
Charles Darwin's contribution to biology - ANS proposing a mechanism for evolutionary
change with abundant and convincing evidence of change in population
natural selection - ANS mechanism for evolutionary change suggested by Charles Darwin;
differential survival and reproduction of individuals in a population.
Year in which On the Origin of Species was published - ANS 1859
Between evolution and natural selection, which theory was accepted first? - ANS evolution
was accepted.
reason scientists rejected natural selection - ANS scientists disagreed about the role and
importance of small variations in natural populations.
natural selection was accepted with the development of; - ANS population genetics
@2026/2027 ALLRIGHTS RESERVED.
, population genetics - ANS Study of allele frequency distribution and change under the
influence of evolutionary processes.
Francisco Ayala's definition of evolution - ANS changes in the genetic constitution of
populations.
population - ANS group of individuals of the same species that occur in the same area and
interbreed
characteristic of population - ANS share a common gene pool
gene pool - ANS all the alleles at all gene loci of all individuals in the population
basic unit of evolution - ANS population
G. H. Hardy and W. Weinberg's contribution to population genetics - ANS they separately
developed a model that showed the process of heredity by itself does not change the genetic
structure of a population in 1908.
Hardy-Weinberg Theorem - ANS the frequency of alleles in the population will remain the
same regardless of the starting frequencies, and this equilibrium genotypic frequencies will be
established after a single generation of random mating.
conditions of Hardy-Weinberg Theorem (5) - ANS 1. large population size (no genetic drift)
2. random mating
3. no natural selection, with all genotypes having equal reproductive success
4. no gene flow (no migration)
5. no NET changes in the gene pool due to mutation.
