In genetics, a heterozygous organism has:

A Two identical alleles for a trait

B Two different alleles for a trait

C No alleles for a trait

D Three alleles for a trait

✓ Correct Answer: Option B

Heterozygous = two different alleles (e.g., Aa). Homozygous = two identical alleles (AA or aa).

💡 Why is B) the correct answer?

The correct answer to the question "In genetics, a heterozygous organism has:" is Option B: Two different alleles for a trait.

The other options — A) Two identical alleles for a trait, C) No alleles for a trait, D) Three alleles for a trait — are incorrect for this Everyday Science question. As explained above: Heterozygous = two different alleles (e.g., Aa). Homozygous = two identical alleles (AA or aa).
