The tight connection between two sister chromatids that is present in the centromere region is not broken until which phase in meiosis?   a) anaphase of meiosis II    b) anaphase of meiosis I    c) prophase of meiosis II    d) prophase of meiosis I    e) metaphase of meiosis II    f) metaphase of meiosis I

Diploid = 2n with n being # of chromosomes so, a) Haploid = n b) Haploid = 3n

Which of the following are differences between mitosis and meiosis I? CHOOSE ALL THAT APPLY. A) Crossing over occurs during meiosis I but not during mitosis B) DNA replication takes place prior to mitosis, but not before meiosis I C) Sister chromatids separate in mitosis, and homologs separate in meiosis I D) Only meiosis I results in daughter cells that contain identical genetic information E) Meiosis I results in two daughter cells, while mitosis results in four daughter cells

What is the purpose of meiosis? In other words, why create haploid cells?

An individual is heterozygous for a reciprocal translocation, with the following chromosomes: A • B C D E F A • B C V W X R ST • U D E F R ST • U V W X Q. Draw a picture of these chromosomes pairing in prophase I of meiosis.

The mosquito, Aedes aegypti, has 3 bivalents (homologous pairs) formed at Meiosis I. How many chromosomes and chromatin strands are present in each of the following stages:

Cleavage is a unique type of cell division that occurs____ a ) during meiosis I only b) during meiosis II only d ) after fertilization of the egg e ) in both meiosis I and II

When is a tetrad specifically formed?  Would it be found in a haploid or diploid cell?  What event caused the mosaic (mixed) appearance of the 2 inside chromatids?
