Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A cell containing 28 chromosomes undergoes mitosis and cell division. How many chromosomes will each of the daughter cells contain?
A
7
B
14
C
28
D
56
Explanation: 

Detailed explanation-1: -∙ If a cell has 28 chromosomes, then after meiosis I the daughter cells will have 14 chromosomes. While after meiosis II they will have 14 chromosomes as meiosis II is an equational division.

Detailed explanation-2: -Answer and Explanation: If a parent cell has 28 chromosomes and undergoes meiosis, the resulting cells will have (c) 14 chromosomes.

Detailed explanation-3: -Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids.

Detailed explanation-4: -If a diploid cell containing 28 chromosomes undergoes meiosis, how many chromosomes will each daughter cell have? EXPLAIN. Each daughter cell will have 14 chromosomes. Meiosis results in haploid gametes, meaning each gamete will have half the original number of chromosomes as the diploid parent cell.

Detailed explanation-5: -During meiosis I, a cell having 28 chromosomes forms two daughter cells having 14 chromosomes each. These cells enter meiosis II and divide. This results in four daughter cells, each having 14 chromosomes.
