Question

While Mitosis produces 2 identical cells for growth, repair and replacement, what is the purpose of Meiosis? (Choose 3) a keeping the chromosome number same as parent cell b increase genetic diversity c produce identical copies of the diploid parent cell d produce non- identical genetically different gametes e reduction of the number of chromosomes, creating a haploid gamet

Answer 1

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.

Answer 2

Answer:

A. produce non- identical genetically different gametes

D. increase genetic diversity

E. reduction of the number of chromosomes, creating a haploid gamete

Explanation:

A. produce non- identical genetically different gametes

B. keeping the chromosome number same as parent cell

C. produce identical copies of the diploid parent cell

D. increase genetic diversity

E. reduction of the number of chromosomes, creating a haploid gamete
