A number of different genes have been identified as affecting skin color and there are probably more as yet unidentified. Each of these genes likely has several regulatory protein factors affecting their expression, and those proteins are coded for by yet more genes. Thus there are many genes involved in determining skin color. A reasonable hypothesis about the geographic distribution of these genes is:

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.
