Question

The graphs below illustrate change in a lizard population over time. Which process most likely led to the change in the lizard population?

A
natural selection acting on a harmful trait

B
natural selection acting on a beneficial trait

C
natural selection acting on a dominant trait

D
natural selection acting on a recessive trait

Answer 1

Answer: Option 'C' is correct.

Explanation:

Dominant traits are those traits which are visibly expressed in the organisms ( here, lizard)

Recessive traits are those traits in which genes are carried but it is not visible itself in the organisms.

Here, we can see that genes of Allele Z is carried by population of lizard in 50 years.

Here, it is natural selection acting on a dominant trait.

Hence, option 'C' is correct.

Answer 2

The process most likely led to the change in the lizard population is the natural selection acting on a dominant trait. So, the correct option is C.

What do you mean by Natural selection?

Natural selection is a selection made by nature on the basis of the most favorable variations among all the variations.

The proportion of Z-allele increases from year 1 to year 50. So, this allele generally contains a dominant trait, because dominant traits are visible in organisms when they are present. While recessive traits are not identified or visible even they are present in organisms.

Therefore, the process most likely led to the change in the lizard population is the natural selection acting on a dominant trait.
