The greatest degree of genetic variation would be found in an offspring resulting from sexual reproduction.
<u>Explanation:</u>
Asexual reproduction produces very less variations. Asexual reproduction requires only one parent and thus the offspring would be very similar to the parent. The chance of variations in offspring is very less.
But the case of sexual reproduction is different. Sexual reproduction involved two parents and each parent contribute equal amount of genetic material to the progeny.
Some characters of the offspring will be like one or the other parent and some characters will be a combination of the characters of both parents
. Such a combination produces variant offspring.
