What is the end result when crossing over occurs between homologous chromosomes?

What is the end result when crossing over occurs between homologous chromosomes?
New genetic combinations are created, resulting in more genetic variation in offspring.
Offspring fail to create the proper proteins that are required for the expression of specific traits.
Offspring fail to receive a complete set of either maternal or paternal DNA, so they are born with genetic disorders.
Fewer genetic combinations are found in the gametes, resulting in less genetic variation in the offspring.

      The correct answer is: New genetic combinations are created, resulting in more genetic variation in offspring.

      Explanation: Crossing over is a process that occurs during meiosis where homologous chromosomes exchange segments of DNA. This recombination results in new allelic combinations in the gametes, thus enhancing genetic diversity in the offspring. This variation is critical for evolution and adaptation in populations.
