The correct answer is Option (1) → 46.
Explanation:
- A zygote is formed when a sperm cell (which carries 23 chromosomes) fertilizes an egg cell (which also carries 23 chromosomes).
- The sperm and egg each contribute half of the total chromosomes, so when they combine, the zygote ends up with 46 chromosomes (23 pairs), which is the typical chromosome number for humans.
- This total includes 23 chromosomes from the mother (egg) and 23 from the father (sperm).
Thus, the zygote has 46 chromosomes in total. |
