An organism with 24 chromosomes in each body cell will produce sex cells with chromosomes.

A)12
B)24
C)48
D)96

Option. A) 12

Explanation:

An organism with 24 chromosomes in each body cell will produce sex cells with 12 chromosomes. The chromosome number is half because meiosis occurs in sex cells in which parent cell is divided into four daughter cells having half number of chromosome i. e. haploid. So the parent cell has 24 chromosome when division occurs, the number of chromosome becomes half i. e. 12.

it would lead to upper respiratory infections and pneumonia.
