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.

Answer:
The correct answers are A and B.
Explanation:
Pleiotropy is defined as "when a single gene affects two or more phenotypic characteristic of an organism.". Phenotypic refers to the traits that can be physically observed or measured in an organism, for example height, hair color etc. So the examples of pleiotropy in the given options are in A and B which describe situations where one gene affects two or more phenotypic traits.
