(i) A husband has 46 chromosomes, his wife has 46 chromosomes. Then why don't their offsprings have 46 pairs of chromosomes, which is obtained by the fusion of male and female gametes? (ii) "Geographical isolation is not a major factor in the speciation of a self pollinating plant species." Justify this statement with the help of an example.

[A]: Random mutations together with genetic drifts and selection pressure establish ge- netic difference and morphological and physiological variations in formerly identical populations. [R]: These differences generally accumulate and thus lead to the establishment of clines, geographical races and finally distinct sub- species.

If trait A exists in 10% of a population of an asexually reproducing species and trait,B exists in 60% of the same population, which trait is likely to have arisen earlier?

In which one of the following species the central atom has the type of hybridization which is not the same as that present in the other three ?

[A]: According to Hardy-Weinburg law both gene frequencies and genotype frequencies will remain constant from generation to gen- eration in an infinitely large interbreeding population.
