Henry 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.

Genetic drift greatly affects small populations, but large population can recover

Genetic drift is the change in the allele frequencies of the population from generation to generations that results because of chance events.  Although genetic drift can be observed in all population sizes but it is more prominent in small population. This is because infrequently occurring alleles get lost in subsequent generations. This was result that Henry saw a decrease in genetic variation in the island species, but not in the mainland species.

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
