which chromosomes are present in round worm​

Answer 1

Answer:

four

Somatic cells of roundworms have four individual chromosomes per cell.

Answer 2

A single gene, TRA-1, determines the sex of these roundworms. If a developing worm has two X chromosomes, this gene is activated and the worm will develop into a female. If there is only one X chromosome, TRA-1 is inactivated, causing the worm to become a male.
