Question
Chapter 11.4, Problem 1R
Summary Introduction
To review:
The process of fertilization that produces a diploid organism with respect to the chromosomes and to know that the cell is diploid.
Introduction:
Haploid cells are those cells that have a single copy of chromosomes (n) inside the nucleus. They only contain half of the chromosomes. The diploid cells have two whole sets of chromosomes (2n). For instance, the muscle and skin cells are diploid, whereas the sperm and ovum are haploid cells.

Which statement is true of meiosis?
1)two identical cells in both divisions
2)the first division produces haploid cells and the second produces diploid cells
3)the first division produces diploid cells and the second produces haploid cells
4) the products of both meiotic divisions are haploid
How are germ cells related to an incorrect meiosis process?
In which meiotic division does the separation of identical chromatids occur? After the end of this process what are the ploidies of the new cells?
