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.

Which of these associations is not correct? seed coat-ovary wall radicle-roots plumule-leaves cotyledons-stored food?
Mars2501 [29]

Seed coat-ovary wall association is not correct.

The seed coat originates from the maternal tissue, that is, the integuments. It is one of the three components of a plant seed, in supplementation to the embryo and the endosperm. The aim of the seed coat is to safeguard the seed from temperature-related, physical or water destruction. It is a protective outer covering of the seed.

On the other hand, the ovary wall refers to the wall of the ovary of a flower that ultimately develops into a pericarp or fruit wall.
