4 A fruit fly's reproductive cells have 4 chromosomes. How many chromosomes do non-reproductive cells have? A) 2 (B) 8 Cannot be determined from the given information

In fruit flies, like many other organisms, the number of chromosomes in non-reproductive (somatic) cells is typically double that of reproductive cells. Since reproductive cells have 4 chromosomes, non-reproductive cells would generally have 8 chromosomes, as somatic cells contain two sets of chromosomes (one from each parent). This basic principle of genetics relates to how organisms maintain genetic continuity and variation through sexual reproduction. So, in this case, the answer is (B) 8. Fun fact: fruit flies, or Drosophila melanogaster, are often used in genetic research because they reproduce quickly and have easily observable traits!
