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?
In asexual reproduction, the reproducing cells
produce a copy of their DNA through some chemical reactions.
However, this copying of DNA is not accurate and therefore, the
newly formed DNA has some variations.
Itcan be easily observed in the above figure
that in asexual reproduction, very few variations are allowed.
Therefore, if a trait is present in only 10% of the population,
it is more likely that the trait has arisen recently. Hence, it
can be concluded that trait B that exists in 60% of the same
population has arisen earlier than trait A.
