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

  • Asexual reproduction results in offspring which are just the identical copies of the parent.
  • Organisms reproducing by asexual reproduction exhibit very less number of variations due to environmental changes or mutations.
  • In such species, a trait may come into existence due to sudden mutation induced by environmental factors.
  • The newly induced trait is then inherited by the future generations through replication over a period of time.
  • Therefore, if a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same population, trait B is likely to have arisen earlier because this trait has been replicating and existing in a higher percentage of the population as compared to trait A.
  • If a trait A exists in 10% of a population of an asexually reproducing species, then it is more likely that this trait has arisen recently.

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.​
