good day
Answer:
Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.
Explanation:
This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).
Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.
Nondisjunction is the failure of one or more pairs of homologous chromosomes or sister chromatic.
