Document Summary

11/18/2015 7:51:00 am: the, the labeling was blank. What is the definition of a homologous pair: same genes. What do you call the equal sharing of genetic material from one chromosome to another: (either crossing over or synapsis) If a cell is 2n=16, what must be true: the gamete has 8 chromosomes. If a cell ranges from 3-6 picograms of dna, where would you expect to find. D. m: more than one above. (i put more than one) I put metaphase i. (the rest of the choices were anaphase i, and different phases in meiosis ii. ) If you have 24 chromosomes in g2, how many chromosomes will you have in anaphase ii: 48. In telophase of mitosis, what would you expect to move towards the remains of the spindle: single unreplicated chromosomes. In anaphase 2, what would you expect to move towards the spindle: single unreplicated chromosomes. During what stage do the chromosomes line up on the equator? : metaphase.

A. The exchange of genetic material between homologous chromosomes during meiosis I.

B. The pairing or tight association of homologous chromosomes in meiosis I. Results in the formation of a tetrad.

C. Non-identical copies of the same chromosome. Present in all diploid cells, even before replication. These chromosomes are the same length and contain genes for the same characteristics, but may have different alleles for each gene. D.

The period of the cell cycle that includes G1, S phase, and G2. E. A structure that develops during cytokinesis in plants.

F. Condensed chromosomes.

G. An invagination that develops during cytokinesis in animal cells.

H. When an organism has two copies of every chromosome (2n).

I. Two identical copies of a chromosome. These are only present after DNA replication.

J. The phase of the cell cycle when DNA is replicated.
