stepan [7]

Answer:

Chromosomes at the conclusion of Meiosis I - $50$

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells

Explanation:

Given

Number of chromosomes in the diploid cells of Aliens from the planet Zorg $= 100$

In the Meiosis I cell division , a cell divides to produce two diploid cells with exactly the same amount of DNA as that of original parent cell.

However, the number of chromosomes is reduced to by half at the end of meiosis I

After Meiosis II, four haploid cells are produces with half the amount of DNA as that of original parent cell

Thus,

Chromosomes at the conclusion of Meiosis I - $50$

Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
