Mitosis results in ______ cells and meiosis results in _______ cells.

diploid, haploid

haploid, diploid

diploid, diploid

haploid, haploid

Explanation / Answer

Question 1 -  To enable an organism to produce gametes (Meiosis leads to development of reproductive cells while mitosis somatic cells)

Question 2-  somatic cells, gametes (the reason same as above question)

Question3- Production of sperm or eggs

Question 4- Sexual reproduction provides more genetic variability(recombination from two organism leads to variation in sexul reproduction other foctor are also participate in variation)

Question 5-  Prophase I of meiosis (crossing over occur in this phase by series of 5 different event )

Question 6- 10 because meiosis produce n chrmosome i.e. new produced cell have half no of chromosme from the parent

Question 7-  Anaphase I of meiosis

question 8 - diploid, haploid
