Explain why eggs and sperm only have half the amount of DNA as a normal body cell.

1 answer:

7 0

They only have 23 chromosomes because they go through meiosis instead of mitosis, in mitosis the chromosomes are duplicated so then you have cells with the full 46 chromosomes, however eggs and sperm go through meiosis which doesn’t duplicate the cells because when a sperm (23 chromosomes) and a egg (23 chromosomes) combine then there’s the full 46 chromosomes for the cell.

I believe the correct answer to this question is B.

This is the correct answer because the other options can be eliminated and this choice represents the proper process described in the question. Answer choice A describes photosynthesis, which is not being asked about in the question. Answer choices C and D are either partially false or describe an unmatching process with the question.

I hope this is correct and helps you!
