100
homologous chromosomes line up at the spindle equator
What is metaphase I?
100
chromatids separate during this phase of meiosis II
What is anaphase II?
100
crossing over occurs in this phase of sexual reproduction
What is prophase I?
100
Chromosomes are alligned at the equator of the cell
What is metaphase?
100
has two chromatids
What is a duplicated chromosome?
200
crossing over occurs during this phase
What is prophase I?
200
chromosomes line up down the equator of the cell
What is metaphase II?
200
Occurs during metaphase I and either the maternal or paternal member of a homologous pair can end up at either pole
What is random allignment?
200
cytokinesis begins
What is telophase?
200
if the diploid number of an organism is 8, the haploid number is
What is 4?
300
each member of the homologous chromosome pair is pulled by the microtubules to opposite poles
What is anaphase I?
300
During spermatogenesis, meiosis occurs this number of times
What is once?
300
randomly selected egg and sperm form a zygote
What is fertilization?
300
MTOC's (microtuble organizing center) migrate to opposite poles
What is prophase?
300
during meiosis there are two rounds of all of the phases except for this one
What is interphase?
400
when chromosomes pair with their homolog
What is a tetrad?
400
chromosomes line up at the spindle equator of the cell
What is metaphase II?
400
the division in which diploid cells produce diploid cells that are genetic copies of the parent cell
What is mitosis?
400
chromosomes begin migrating to opposite poles
What is anaphase?
400
division of the cytoplasm
What is cytokinesis?
500
when homologous chromosomes come into close contact during meiosis I
What is synapsis?
500
nucleus reforms and the cell has half the number of chromosomes than the original cell
What is telophase II?
500
Type of cell that has centrioles which participate in the formation of aster fibers during mitosis
What is an animal cell?
500
Type of cell that forms a cell plate by fusing vesicles together
What is a plant cell?
500
G1, S, and G2 are parts of this phase
What is interphase?
