Answer:
It helps insure the survival of a species in a whole.
Explanation:
Allows different species, for example dolphins or meerkats, to mate and ensure survival in their habitats.
Crossing over does helps in genetic diversity as it provides with new genes combinations. In crossing over, chromatids exchange genetic information during the meiosis. This mixing of genetic information provides the offspring with its own unique genetic makeup with some similarities with the parent’s genetic system. Crossing over is very beneficial in terms of giving the offspring more variability that helps in becoming more resistant to a disease and be a better version than parents.
