Suppose that a few individuals of a lizard species are transported on a log that floats from the mainland, where the lizard is abundant, to a distant island, where prior to this event no lizards (of any species) existed. the environmental conditions on the island are similar to those on the mainland. a small population of this lizard becomes established on the island; within a few years, allele frequencies in the island population differ greatly from those in mainland populations. which of the following is the most likely cause of the genetic differences between the island and mainland populations? a. natural selectionb. genetic driftc. mutationd. gene flow

B. genetic drift

Explanation:

Suppose that a few individuals of a lizard species are transported on a log that floats from the mainland, where the lizard is abundant, to a distant island, where prior to this event no lizards (of any species) existed. The environmental conditions on the island are similar to those on the mainland. A small population of this lizard becomes established on the island; within a few years, allele frequencies in the island population differ greatly from those in mainland populations. Which of the following is the most likely cause of the genetic differences between the island and mainland populations is genetic drift

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.

e) all of the above
