The total number of genes in humans is far less $(< 25,000)$ than the previous estimate (up to $1,40,000$ genes). Comment.

(N/A) The human genome project revealed that the total number of genes in humans is approximately $20,000$ to $25,000$,which is significantly lower than the earlier estimates of $80,000$ to $1,40,000$ genes.
This discrepancy exists because a large portion of the human genome consists of non-coding repetitive sequences.
Repetitive sequences are stretches of $DNA$ that are repeated many times,sometimes hundreds to thousands of times.
These sequences are thought to have no direct coding functions,though they provide insights into chromosome structure,dynamics,and evolution.
Ultimately,less than $2$ percent of the human genome actually codes for proteins.
