Genetic drift is the process where there are random fluctuations in the gene frequencies within a population. this can eventually lead to the new population being genetically distinct from the original. due to this difference, there is a hypothesis that genetic drift leads to the formation of new species. what is this process known as?
a) gene flow
b) speciation
c) natural selection
d) genetic diversification

Ry was studying two populations of the same species of lizards. one population lived on an island and the other lived on the mainland. both populations were affected by a hurricane that hit the island and the mainland with equal force. a year later, henry was testing the gene frequency and saw a decrease in genetic variation in the island species, but not in the mainland species. which best describes a conclusion he might have reached? gene flow greatly affects small populations, but large populations can recover. genetic drift greatly affects small populations, but large populations can recover. gene flow greatly affects large populations, but small populations can recover. genetic drift greatly affects large populations, but small populations can recover.
