Crossing over can BENEFIT eukaryotic organisms by which of the following?

Select all correct responses.

a
Crossing over creates diploid cells from haploid cells.
b
Crossing over increased genetic variation- diversity.
c
Crossing over uses more energy and is vulnerable to errors.
d
Crossing over results in the production of genetically unique organisms.

1 answer

The correct responses regarding how crossing over can benefit eukaryotic organisms are:

b. Crossing over increased genetic variation- diversity.
d. Crossing over results in the production of genetically unique organisms.

Options a and c do not correctly represent the benefits of crossing over in eukaryotic organisms. Option a is incorrect because crossing over does not create diploid cells from haploid cells; it occurs during meiosis and contributes to genetic variation in haploid gametes. Option c, while highlighting that crossing over requires energy and can lead to errors, does not describe a benefit.
