Answer:
Sexual reproduction produces genetically different offspring from two parents while asexual reproduction produces genetically identical offspring from one parent.
Sexual reproduction will see to the offspring taking half of their genetics from the father (male), while the other half comes from the mother (female). The offspring would further inherit based on whether the traits are dominant or recessive. However, in asexual reproduction, there is only one parent, so all the traits are passed down.
