Although snapping shrimp in the Atlantic and Pacific look similar, they are distinct species. Explain how you predict speciation occurred using the appropriate terms out of this word bank: allopatric speciation, sympatric speciation, gene flow, genetic drift, geographic isolation

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.
