Which is true about external Fertilization?
B. Does not require the union of gametes
External fertilization is defined as the discharge of both sperm and eggs into an external environment, with the sperm fertilizing in the egg outside of the organism, as in spawning. External fertilization is most common in aquatic habitats when both eggs and sperm are discharged. Fertilization can begin after the sperm has reached the egg. The majority of external fertilization occurs during the spawning phase when one or more females release their eggs and one or more males discharge sperm in the same location at the same time. The temperature of the water or the amount of daylight may cause the reproductive material to be released. Crustaceans (like crabs and shrimp), mollusks (like oysters), squid, and echinoderms (like sea cucumbers) all spawn. This enables the female to choose a certain man. The egg and sperm release trigger (spawning) leads the egg and sperm to be concentrated in a limited region, increasing the chances of fertilization.
