Thirty people are selected for a long-term mission to colonize a planet many light-years away from earth. the mission is successful and the population rapidly grows to several hundred individuals however, certain genetic diseases are unusually common in this group, and the group's gene pool is quite different from that of the earth population they have left behind. which of the following phenomena has left its mark on this population? a. founder effectb. adaptive effectc. high rates of mutationd. natural selection

The correct answer will be Option- founder effect

Explanation:

The founder effect is the effect observed in a population caused by the loss of the genetic variation. The genetic variation is lost as a result of the establishment of the new population caused by the migration of the few numbers of individuals from a larger population.  

This loss of genetic variation leads to variation in the genotype and phenotype of the newly established population.

Since in the given question the gene pool of the new population on the new planet is different from the parent population leads to a phenomenon called founder effect.

Thus, the founder effect is the correct answer.
