Which human cells never have 23 pairs of chromosomes?

A.
blood cells

B.
nerve cells

C.
mature sex cells

D.
mutant cells

Answer 12

Human sex cells which only have a haploid number of chromosomes. 23 total chromosomes. So it's C...

Answer 13

is C right??

Answer 14

yes :)

Answer 15

u say 23 pair
in mature blood cell
there is no nucleus.
in mature sex cell there is only 23 pair of genes
in mutant cell genes may be more or less than 23 pair (eg klinefelter syndrome)
so at lat nerve cell is left
they have 23 pair of gens
so b is the right option
