A cell from a fruit fly Drosophila melanogaster has a diploid number 2n of 8. How many chromosomes would be in a fruit fly gamete?

  • A: 16
  • B: 8
  • C: 4
  • D: 2

Explanation

The text states that gametes are haploid n , meaning they contain a single set of chromosomes. If the diploid number 2n is 8, then the haploid number n is half of that, which is 4. The text provides this exact example for Drosophila melanogaster.
