Darwin's finches are a good example of:

1. industrial melanism

2. connecting link

3. adaptive radiation

4. convergent evolution

Given that the frequency of children homozygous for the recessive allele for cystic
fibrosis is about 0.0016. What is the frequency of heterozygotes in the population? [Cystic fibrosis is inherited as an autosomal recessive disorder].

1. 0.960

2. 0.077

3. 0.040

4. 0.923

Peripatus is a connecting link between:

1. Ctenophora and Plantyhelminthes

2. Mollusca and Echinodermata

3. Annelida and Arthropoda

4. Coelenterata and Poriphera

One of the important consequences of geographical isolation is:

1. no change in the isolated fauna

2. preventing speciation

3. speciation through reproductive isolation

4. random creation of new species

The finches of the Galapagos islands provide evidence in favour of:

1. special creation

2. evolution due to mutation

3. retrogressive evolution

4. biogeographical evolution

2. Neanderthal

3. Pre-neaderthal

4. None of these

Darwin’s finches represent:

1. Morphological variations

2. Geographical isolations

3. Climate variations

4. Reproductive isolation

Hardy-Weinberg equilibrium is known to be affected by gene flow, genetic drift, mutation, genetic recombination and:

1. evolution

2. limiting factors

3. saltation

4. natural selection
