A diploid organism has a somatic chromosome number of 16. The centromeres of the 8 homologous pairs are designated as Aa, Bb, Cc
Simora [160]

Answer:

Option C, 256

Explanation:

The diploid number of chromosomes are represented as 2N.

Here the somatic chromosome number is 16 which can be represented in the "2N" format with N being equal to 8.

Now, as we know that the total number of chromosomal combination with chromosome number being

16 \\OR\\2 N(8)

is equal to

2^N\\

Substituting the given values in above equation, we get -

2^8\\= 256\\

Therefore, total of 256 different combinations of centro-meres could be produced during meiosis.

Hence, option C is correct
