A scientist is studying two types of worms. Worm X has DNA identical to its parent. Worm Y has a combination of DNA from two parents. The scientist determines that one of the worms has a survival advantage over the other worm.

Question

Which statement correctly summarizes this conclusion?

1.Worm X reproduces asexually, which gives it genetic variation.
2.Worm Y reproduces sexually, which gives it genetic variation.
3.Worm Y reproduces asexually, which gives it more DNA.
4.Worm X reproduces sexually, which gives it more DNA.

Answer 1

The correct statement that summarizes the conclusion is:

2. Worm Y reproduces sexually, which gives it genetic variation.

This statement correctly identifies that Worm Y has a combination of DNA from two parents, indicating it reproduces sexually, which typically provides genetic variation that can confer survival advantages in changing environments.
