Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The Chromosome number in a certain fish is 20. How many chromosomes would be found in bone cells of this fish?
A
10
B
20
C
23
D
40
Explanation: 

Detailed explanation-1: -Therefore, our answer is 20 chromosomes. Mm Okay, so this is our answer. 20 chromosomes because bone cell only undergoes mitosis and not muses. If the question is how many chromosomes are in the egg cell or in the sperm of the fish, then we will answer half of the deployed, which is Hap Lloyd and that would be 10.

Detailed explanation-2: -Corn has diploid number of chromosomes. It is thus given as 2n = 20.

Detailed explanation-3: -Complete answer: If an organism has 20 chromosomes, then the number of chromosomes the daughter cells have after mitosis is 20 because when a cell divides by the process of mitosis it produces two clone daughter cells having the same number of chromosomes (20) as the parent cell has.

Detailed explanation-4: -When two reproductive cells unite, they become a single cell, i.e., zygote that contain two copies of each chromosome. Thus, the monkey would have 42 chromosomes in its zygote.

Detailed explanation-5: -Explanation: Haploid means half, and diploid means double of the half, and so its diploid number will be 20⋅2=40 if its haploid number is 20 .
