In an asexually reproducing species, if a trait X exists in 5% of a population and trait Y exists in 70% of the same population, which of the two trait is likely to have arisen earlier? Give reason.

In an asexually reproducing species, traits are passed on to offspring through direct replication of the genetic material of the parent. Unlike sexual reproduction, where genetic diversity arises through recombination, asexual reproduction involves the transmission of identical genetic material from one generation to the next.

Given that trait X exists in only 5% of the population, while trait Y exists in 70% of the population, it’s reasonable to infer that trait Y is likely to have arisen earlier. Here’s the reasoning:
• Stability of Trait X: Trait X being present in only 5% of the population suggests that it may not have spread as widely or as quickly. It could be a relatively new mutation or a less advantageous trait.
• Widespread Presence of Trait Y: Trait Y, on the other hand, being present in 70% of the population, indicates that it has had more time to spread and become prevalent. Traits that confer a selective advantage, promote survival, or enhance reproduction are more likely to become widespread in a population over time.
• Selection and Replication: In asexually reproducing species, the traits that offer a survival or reproductive advantage are more likely to be passed on to a larger proportion of the population with each generation. Traits that enhance an organism’s ability to survive and reproduce tend to become more prevalent over time.

In summary, the higher prevalence of trait Y in the population suggests that it is likely to have arisen earlier and had more time to spread through successive generations, possibly due to providing some selective advantage in the particular environment or conditions of the population.
