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.

Sharks evolved several million years ago, before dolphins. Sharks adapted to the water with their hydrodynamic bodies. Dolphins evolved long after sharks from land mammals and adapted to water. Dolphins are warm-blooded mamals while Sharks are cold – bodied mammals.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

ya the other dude is right
