alleryApproximately how many genes does the human genome contain (per HGP)?
A1 million
B~30,000
C100,000–140,000
D5,000
Answer & Solution
Correct answer: B. ~30,000
HGP revealed **~30,000 genes** in the human genome — much lower than pre-project estimates of 80,000–140,000. The 'gene count surprise' was a key HGP finding.
complexity comes from regulation and splicing, not gene count.
