Answer:
Answer is D.Produce non-identical genetically different gametes and reduction of chromosomes,creating a haploid gamete.
Explanation:
Meiosis is essential for sexual reproduction.In humans diploid gamete-mother cells or germ line undergo meiosis to produce haploid gametes.
The chromosomes pairs of each parent undergo crossing over during meiosis.so daughter cells i.e gametes have genetic variations.When gametes fuse and form zygote ,its genetic make up is different from both parents.thus meiosis allows a species to bring variations in next generations.Benenficial variations help organisms to adapt to the changes in environment.
The structure labeled X in the diagram is a membrane protein.
