Option 1: Variation is minimum in asexual reproduction.

This statement is not true. Asexual reproduction involves the production of offspring that are genetically identical to the parent organism. While there may be some variations due to genetic mutations, the overall level of variation is lower compared to sexual reproduction where there is a combination of genetic material from two parents. Therefore, asexual reproduction tends to have less variation.

Option 2: All variations in a species have equal chances of survival.

This statement is not true. Variations in a species do not have equal chances of survival. Some variations may provide advantages in certain environments, increasing the chances of survival and reproductive success. These advantageous variations are more likely to be passed on to future generations, leading to the evolution of the species. On the other hand, variations that don`t provide any advantages or are detrimental to survival may not be passed on or may decrease in frequency over time.

Option 3: Changes in genetic constitution result in variation.

This statement is true. Variations occur as a result of changes in the genetic constitution of individuals. These changes can be caused by genetic mutations or recombination of genetic material during sexual reproduction. Genetic variation is an important factor in the evolution of species.

Option 4: Variants can
