Question

meiosis differs from mitosis in that
A) it occurs only in the reproductive tissues that produce gametes.
B) the chromosomes are duplicated twice.
C) the resulting cells are polyploid.
D)the chromosomes pairs do not separate
E) the daughter cells are all genetically identical to the mother cell and each other.

Answer 1

i say its (A) cos the gametes ONLY undergo meiosis

cos in (B) the chromosomes are ALSO duplicated in mitosis ( i guess..)

(C) i dont have an accurate answer for this one.. but look at this: (it will help you ALOT) http://en.wikipedia.org/wiki/Polyploid

(D) yes, chromosomes pairs do separate and it actually separates during ANAPHASE 1

(E) umm... i dont have an answer to this one either.. -sorrryyyyyy- BUT I DONT THINK SO..

Answer 2

okay thank you

Answer 3

I am sure it is A because chromosomes are duplicated once and in C no they are not polyploid, in C actually the chromosomes do separate and in E no the daughter cells have different genetic material from their mother because crossing-over occurs.
