Question
explain the answer too!blubber is a thick layer of fat tissue found under the skin of all elephant seals, conveying an advantage in making them tolerate cold water temperatures. this trait has a strong genetic basis, and all elephant seals have the genotype that produces blubber. is this trait currently undergoing selection?
a. probably, because it confers an advantage
b. probably not, because it is now produced by the seals' environment rather than genes
c. probably not, because there is little genetic variation and so it can't respond to selection
d. definitely, because it is an adaptation
