Sexual reproduction produces genetically different offsprings which do possess variations, hence better chance to survive in the environment.
Option C
<h3><u>Explanation:</u></h3>
Sexual reproduction is the process of reproduction where there's a fusion of gametes from a male and female of the same species, resulting in a zygote and eventually an offspring. Sexual reproduction is very advanced type of reproduction which is very expensive for an organism. Much of the energy of the organism is spent to produce gametes and other necessary processes for reproduction.
Gametes of the sexual reproduction is produced mainly by means of meiotic cell division. This involves crossing over and chaismata formation which helps in genetic variations in the offspring. These variations help the species to survive unknown changes in environment, and helps to adapt quickly lessening the chances of extinction. So sexual reproduction has modified various times in different groups of species.
