In one species of shark, having a curved dorsal fin is dominant over a straight dorsal fin. this image represents a gene pool for a population of sharks off the coast of hawaii. calculate the allele frequencies, making sure to show your work. furthermore, discuss whether this population has a high or low genetic variation for the dorsal fin trait. finally, predict what would happen to the frequencies of d and d in the gene pool if having straight dorsal fins became advantageous.
