According to Hardy - weinberg principle, the frequency of homozygous recessive (aa) individuals in a population is denoted by

1. $p^2$

2. 2pq

3. $q^2$

4. p + q

Match column I and column II with respect to cranial capacity

       Column I                      Column II

a. Homo erectus               (i) 650 - 800 cc

b. Homo sapiens              (ii) 1650 cc

c. Cro-Magnon man         (iii) 1400 cc

d. Homo habilis                (iv) 900 cc

Choose the correct option

1. a(i), b(ii), c(iii), d(iv)

2. a(ii), b(iii), c(iv), d(i)

3. a(iv), b(iii), c(ii), d(i)

4. a(iii), b(iv), c(i), d(ii)

Hardy-Weinberg equation is used to check

1. Size of population 

2. Whether evolution is occuring in a population or not

3. Average lifespan of a population

4. Maximum life expectancy of a population

Adaptive radiation can be observed in all cases except

1. marsupial radiation

2. Variety of beaks in Darwin's finches

3. Placental diversification in North American

4. Wing structure of butterfly, bat and bird

The evolutionary process giving rise to new species
adapted to new habitats and ways of life is called
adaptive radiation. For example,

1. Darwin’s finches in Galapagos Islands.
2. Australian marsupials that radiated to form new
species.
3. Wolf and Tasmanian wolf.
4. Both (a) and (b)

Select the incorrect match with respect to placental mammals and Australian marsupials.

(1) Lemur : Spotted cuscus

(2) Bobcat : Tasmanian tiger

(3) Anteater : Numbat

(4) Koala : Flying squirrel

Theory of spontaneous generation was rejected because:

Which of the following options is not correct regarding the early atmosphere?

(A) Oxygen was totally absent

(B) Atmosphere was reducing

(C) Temperature was high

(D) Presence of free $H_2$ molecules

(E) Presence of molecules like $C{H}_4,$ $N{H}_3,$ $H_{2}O$ vapours

1. A, D and E

2.  A and D

3. D and E

4. A only

If frequency of 'A' allele is 0.4 than, find out the frequency of 'B' allele and heterozygous genotype in a random mating population at equilibria.

1. 0.6 an 0.24

2. 0.6 and 0.96

3. 0.6 and 0.48

4. 0.6 and 0.50

The correct statement about the nature of evolution and natural selection is

1. Evolution is a process while natural selection is the end result of a process which is unknown.

2. Natural selection is a process while evolution is the end result of a process which is unknown.

3. Both evolution and natural selection are the end results of a process which is unknown.

4. It is still unclear whether evolution and natural selection are process or end results of unknown processes.
