Question
How many chromosome combinations are present in any gamete?
- 8 million
- 8 trillion
- 2 million
- 3 billion
Hint:
Humans have 23 pairs of chromosomes. Also consider combination of male and female gametes.
The correct answer is: 8 million
- Humans have 23 pairs of chromosomes.
- As a result, an individual can produce 223 different gametes.
- In sexual reproduction, two gametes are involved. As a result, (223)2 combinations are possible.
- Hence, around 8 million chromosomal combinations are possible.
