Two human beings who can both roll their tongues produced 11 children. 3 of these children could not roll their tongues and 8 children could roll their tongues. (a) Which trait (rolling or not rolling) is controlled by the recessive allele? (b) State all possible genotypes of the F1 generation of the cross. Show the inheritance of the tongue rolling in humans in the given example using a suitable cross. What percentage of offspring will show the same genotype as the parents? OR (c) If one of the parents could not roll their tongue, with the help of a cross, calculate the ratio of tongue- rollers to non-tongue-rollers in the off springs.

The defination of species says ' The organisms which can reproduce among themselves giving rise to new individuals having reproductional potentialities'. Now when new species are produced due to the isolation of the individuals of a species byb environmental barriers then the individuals reproduce with rthe members of the other species giving rise to another species which is not possible because the offsporings formed by the copulation of individuals of different species give birth to sterile organism. Then hgow are new organisms formed due to geographical isolation?
