Which process contributes to genetic variability during meiosis?
Understand the Problem
The question is asking about the processes that contribute to genetic variability during meiosis, specifically identifying the correct option from the list provided.
Answer
Independent assortment and crossing over contribute to genetic variability during meiosis.
Genetic variability during meiosis is mainly contributed by independent assortment of gametes and genetic recombination during crossing over.
Answer for screen readers
Genetic variability during meiosis is mainly contributed by independent assortment of gametes and genetic recombination during crossing over.
More Information
During meiosis, independent assortment refers to how different genes independently separate from one another when reproductive cells develop. Crossing over is a process where homologous chromosomes exchange segments, resulting in new allele combinations.
Tips
A common mistake is confusing independent assortment and crossing over with mutation, which is not a main process of genetic variability in meiosis.
