1
In which phase of meiosis do homologous chromosomes align as tetrads in the middle of the cell?
metaphase II
metaphase I
prophase II
prophase I
2
Which description best fits the activity of a cell during interphase?
The cell splits in two.
The cell differentiates to have a new function.
The cell carries on metabolism and normal functions.
The cell splits in two, w/ 1/2 normal number of chromosomes.
3
Describe the actions of the cell’s chromosomes during metaphase, a stage of mitosis.
They move toward the poles of the cell.
They condense to become chromatin.
They duplicated.
They line up in the middle of the cell.
4
What is the significance of meiosis in helping to maintain continuation of a species?
Meiosis passes traits thru gametes in asexual reproduction.
Equal numbers of eggs and sperm are produced by meiosis.
Meiosis produces eggs and sperm that are alike.
Meiosis produces genetic variation in the gametes.
5
During which phase of mitosis are sister chromatids pulled away to opposite ends of the cell?
telophase
prophase
metaphase
anaphase
6
What process is taking place in the illustration shown below?
prophase II
fertilization
polyploidy
crossing over
7
Which description best identifies characteristics of asexual reproduction?
two parents, gamete union, offspring similar to parents
one parent, no gamete union, offspring identical to parent
one parent, gamete union, offspring similar to the parent
two parents, no gamete union, offspring identical to parent

16
The timing and rate at which a cell divides is coordinated by which complexes?
nuclear division
DNA replication
protein synthesis
cyclin/CDK combinations
17
In which stage of meiosis does number of chromosomes decrease from diploid (2n) to haploid (n)?
