Answer:
D. The offspring of multi-cellular organisms tend to be identical to the parent.
Explanation:
The offspring of multi-cellular organisms which reproduce through sexual mode can never be identical to the parents because of <u>crossing over</u> which is a phenomenon which occurs during <u>meiosis</u>. All the individuals which have sexual dimorphism and reproduce sexually have germ cells in their gonads. Meiosis is a type of cell division which occurs only in germ cells not in somatic cells. <u>During meiosis the genetic material from both the parents is exchanged leading to new combinations of genes</u> as a result of which offspring is neither 100% identical to father nor to the mother. Offspring displays traits which are a combination of both the parents thereby showing variability.
