7. Why is approximately 50% of any individual's DNA inherited from that individual's father?
Strike441 [17]

Answer:

B. It was passed to the individual by a gamete from the father.

Explanation:

<u>DNA is transferred</u> to the next generation <u>via gametes</u>, which are produced during <u>meiosis</u>. During meiosis, <u>half of the genetic material</u> is <u>transferred</u> from parent cell to their gametes. Therefore, among the given options, only <u>B is correct</u>.

Option A is not correct because it talks about <u>somatic cells;</u> whereas, in somatic cells, <u>genetic material is not transferred half</u> rather duplicate first and then a complete duplicated set of genetic material is transferred.

Option C is also not correct because only <u>one gamete (sperm)</u> fertilizes the egg. Hence, not half of his cells descend from father gamete. Similarly, option D is also incorrect because it is not possible to descend half of the nuclei from the father to the offspring.
