BIOXII07:EVOLUTION

Assertion : Founder effect may lead to formation of new species Reason : Founders carry all the parental gene pool to a new location
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
When a few individuals from some large population invades a new or an isolated geographical region, these become the founder members. These founders carryon a limited portion of parental gene pool. Some times they form a new species.

Which of the following statement is false?
1 Speciation is generally a function of time, for tropics, unlike temperate regions subjected to frequent glaciations for past.
2 The sum total of genes of all the species in an area constitutes the gene pool.
3 The gene frequency refers to the proportion of an allele in the gene pool as compared with other alleles.
4 Both (1) and (3)
Explanation:
Gene pool is the set of all genes (genetic information) of a single species in any population.

Identify the correct statement
1 Genetic variability is produced by gene mutations
2 Accumulation of useful mutations through ages has led to the creation of new species of living beings
3 Genetic variability provides raw materials for the operation of natural selection and reproductive isolation
4 All the above
Explanation:
Genetic variability is the change in the sequence of the gens due to mutations. These mutations has led to new species generation. The so evolved species are selected in the environment based on natural selection.
BIOXII07:EVOLUTION
346517
Which of the following statement is false?
1 Microbial experiments show that pre- existing advantageous mutations when selected will result in observation of new phenotypes. Over few generations, this would result in Speciation.
2 The sum total of genes of all the species in an area constitutes the gene pool.
3 The gene frequency refers to the proportion of an allele in the gene pool as compared with other alleles.
4 None of the above
Explanation:
Gene pool is the set of all genes (genetic information)of a single species in any population.
