How many genes are present on chromosome $1$?

In addition to the human genome sequence,draft or finished genome sequences existed for eight model organisms by $2002$. Which of the following organisms are not the part of that group of eight model organisms?

Which of the following is not a salient feature of the human genome?

In humans, the first chromosome has the most genes $(2968)$ and the $Y$ chromosome has the fewest genes $(231)$.

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

When was the sequencing of chromosome $1$ completed?
