Question

Which organism has the maximum number of chromosomes?

• A. Horse
• B. Drosophila
• C. Human (46)
• D. Ascaris

Hint:

The number of chromosomes varies greatly among different species. While humans have 46 chromosomes, many animals and plants may have more or fewer chromosomes depending on their genetic makeup.

Answer 1

The Correct Option is A

To determine which organism has the maximum number of chromosomes, we need to compare the chromosome count of each organism listed:

• Horse: Horses have 64 chromosomes.
• Drosophila (fruit fly): Drosophila has only 8 chromosomes.
• Human: Humans have 46 chromosomes.
• Ascaris: Ascaris, a genus of parasitic nematode worms, typically has a low number of chromosomes (e.g., Ascaris suum, has 4 chromosomes).

From this comparison, we see that the horse, with 64 chromosomes, is the organism with the maximum number of chromosomes among the options provided.
