Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A diploid cell in a buffalo has 60 chromosomes. A sperm or egg cell in a buffalo can be expected to have
A
60 Chromosomes
B
120 Chromosomes
C
30 Chromosomes
D
15 Chromosomes
Explanation: 

Detailed explanation-1: -The bison’s sperm cells would have 30 chromosomes because the sperm cells are gametic cells which are haploid cells.

Detailed explanation-2: -If a cell has 15 pairs of chromosomes (n = 15), it has 30 chromosomes (2n = 30). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes.

Detailed explanation-3: -A cow has 60 chromosomes in one of its somatic cells.

Detailed explanation-4: -The diploid number can be calculated by multiplying the haploid number by 2. The variable ‘N’ represents the number of chromosomes in the genome. Thus, the haploid number of chromosomes is equal to N. The diploid number of chromosomes is equal to 2N.

Detailed explanation-5: -What is the haploid chromosome number of cattle? The diploid number for cattle is 60 (2n=60). How many PAIRS of chromosomes do cattle have? The diploid number for cattle is 60 (2n=60).
