meiosis does not occur in reproductive cells
c)
the cells produced at the end of meiosis are genetically identical to the parent cell
d)
The cells produced at the end of meiosis contain half the number of chromosomes as the parent cell
6.
Which of the following best describes meiosis?
a)
It is carried out in all tissues theat require cell replacement
b)
It occurs only in cells in the reproductive structures of an organism
c)
It happens in all of the tissues except the brain and spinal cord
d)
It is the first stage of mitosis
7.
Which best describes the process shown?
a)
mutation in which the DNA content of the gene is ltered
b)
segregation of sister chromatids
c)
condensation and segregation of the alleles
d)

a)
n+n=2n
b)
n=n
c)
2n=n+n

2n=2n
9.
Which of the following best explains why the chromosome number is an even number in organisms?
a)
It is only by coincidence, many organisms have an odd number
b)
The diploid number is always even so that when mitosis occurs each cell gets the same number of chromosmes
c)
The diploid chromosome number represents pairs of chromosomes, one from ech parent, so that it is always an even number
d)
Chromosomes double very time the cell divides, so after the first division, the number is always even
