ASEXUAL REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The offspring of sexual reproduction are genetically ____
A
identical
B
the same
C
different
D
clones
Explanation: 

Detailed explanation-1: -During sexual reproduction the genetic material of two individuals is combined to produce genetically diverse offspring that differ from their parents. The genetic diversity of sexually produced offspring is thought to give species a better chance of surviving in an unpredictable or changing environment.

Detailed explanation-2: -Sexual reproduction has the potential to produce tremendous genetic variation in offspring. This variation is due to independent assortment and crossing-over during meiosis, and random union of gametes during fertilization.

Detailed explanation-3: -In asexual reproduction, only a single parent is involved. So, the offspring produced are genetically identical to the parent and to each other as well. Such offspring are called clones. Hence, the offspring are genetically identical to themselves and their parents.
