- In a hypothetical human population in
Hardy-Weinberg equilibrium, the
frequencies of the alleles IA, IB and i are
respectively 0.1, 0.3 and 0.6. What
percentage of the population is expected
to have ‘B’ type blood?
(a) 27 (b) 9 (c) 36 (d) 45
- In a population of 1,000 individuals,
400 are homozygous Rh+(DD), 240 are
heterozygous Rh+(Dd) and 360 are Rh-
(dd). The frequency of recessive allele (d)
in that population is
(a) 0.48 (b) 0.6 (c) 0.52 (d) 0.96
- Read the given statements
i. Theory of pangenesis was given by
Lamarck to explain the inheritance of
acquired character.
ii. According to Ernst Haeckel, Ontogeny
is recapitulation of phylogeny i.e., the
development of an organism reveals the
evolutionary history.
iii. In modern synthetic theory, the unit of
evolution is individual.
iv. Weismann’s theory of germplasm
rejected Darwin’s theory of
pangenesis.
(a) i, ii and v are correct
(b) ii & iv are correct
(c) i, iv & v are correct
(d) i, ii, and iv are correct
- Mark the incorrect statements
(a) Homology in vertebrates brain indicates
their common ancestry
(b) The idea of survival of fittest of Alfred
R Wallace was based on his studis on
Galapagos islands
(c) The fitness of the individuals, according
to Charles Darwin, means reproductive
fitness
(d) All of the above
- Fishermen use nets of a large mesh size to
capture larger adult fish, leaving smaller
adults.
This would result in
(a) Disruptive selection as more fish acquire
peripheral character value at both ends
of the distribution curve
(b) Stabilizing selection as individuals
with mean weight have maximum
chance of survival
(c) Directional selection leading to an
increase in the mean weight
(d) Directional selection leading to a
decrease in the mean weight
- Which of the following statements are True
(T) or False (F).
i. Homo sapiens arose in Africa and

ii. Agriculture came around 18000 years
ago and human settlement started.
iii. During ice- age between 75000-10000
years ago modern Homo sapiens arose
