Question
What is the significance of crossing over?
Cell division
Mutation
Genetic variation
All of the above
Cell division
Mutation
Genetic variation
All of the above
Hint:
Crossing over is the reason why parents and offsprings aren't identical to each other.
The correct answer is: Genetic variation
Crossovers are important for the normal segregation of chromosomes during meiosis. Crossovers also contribute to genetic variation, as chromatids held together by centromeres are no longer identical due to the exchange of genetic material during crossovers.
