Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following sentences about meiosis are correct?I. Meiosis halves the amount of DNA.II. Meiosis enables sexual reproduction.III. Meiosis results in the genetic diversity of offspring.IV. The first meiotic division in eukaryotes is similar to mitosis.V. Meiosis in higher eukaryotes occurs in somatic cells and gametes.
A
I, II and IV
B
I, II and III
C
II, III and V
D
II, III and IV
Explanation: 

Detailed explanation-1: -So, the correct answer is ‘Meiosis produces gametes that contain one complete haploid set of chromosomes’

Detailed explanation-2: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Detailed explanation-3: -At the conclusion of meiosis, there are four haploid daughter cells that go on to develop into either sperm or egg cells.

Detailed explanation-4: -Meiosis is a process where a single cell divides twice to produce four daughter cells. These daughter cells are haploid, which means that they contain half the number of chromosomes of the parent cell. They are genetically distinct cells sex cells-sperm in males, eggs in females.
