Which of the following is the best definition for MEIOSIS?
the process of two haploid cells uniting
the counting of chromosomes within a diploid cell
a two-step process that reduces the number of chromosomes in half such that there is only one copy of all the chromosomes
the equational division of a cell into two identical copies
What is unique to Prophase I- is that the duplicated chromosomes pair up to form _______.
a centrosome
a tetrad
the mitotic spindle
sister chromatids
In which stage of MEIOSIS does crossing over occur? (The exchange of genetic material between chromosomes in a tetrad.)
Anaphase I
Metaphase I
Prophase I
Telophase I
In Anaphase I, the _________ are separated by the pulling of the spindle fibers to opposite poles of the cell.
homologous pairs of chromosomes
sister chromatids
centromeres
centrosomes
How many cells are formed at the end of Meiosis II?
2
3
4
8
Which of the following are CORRECT observations about the differences between MITOSIS and MEIOSIS? (Check all that apply.)
Mitosis produces cells that identical to the parent cell.
Meiosis produces cells that have half the number of chromosomes as the parent cell.
All cells go through INTERPHASE as part of the cell cycle, whether it goes to mitosis or meiosis next.
In both types of cell division, the chromosomes are only duplicated once.
Only in Mitosis, do you see chromosomes pair up to form a tetrad.
