A) Haploid DNA content
B) Huge variations in C-values between species
C) Constant C-value for all species
D) Diploid DNA content
Correct Answer: B
Solution :
Each species has a characteristic content of DNA which is constant in all the individuals of that species and has thus been called the C-value. Eukaryotes vary greatly in DNA content but always contain much more DNA than prokaryotes. Lower, eukaryotes have less DNA such as nematode Caenorhabditis elegans which has only 20 times more DNA than E. Coli or the Drosophila which has 40 times more DNA (ie, 0.18 pg). Man has about 3 pg of DNA per haploid genome. This huge variation in C-value between species is called C-value paradox.
