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 occurs during meiosis when homologous chromosomes exchange segments of DNA. This process creates new combinations of alleles, which increases genetic diversity among the offspring. This variation is essential for evolution and adaptation within a population.
