Answer:
Since sister chromatids are identical, genetic variation will not be produced in the daughter cells.
Explanation:
Sister Chromatid Exchange (SCE):
- This is a rare recombination phenomena that entails recombination and crossing over between two sister chromatids.
- This is contrary to normal recombination in which crossing over between non-sister chromatids takes place, producing genetically variable daughter cells.
- Exchange of genes between sister chromatids does not produce genetic variations.
- SCE is actually an indicator of chromosomal instability and DNA repair and replication malfunction.
- SCE is observed to be increased in pathological conditions like Bloom syndrome (genetic disorder) and Behcet disease (chronic inflammatory disorder) etc.
