Mitosis –vs- Meiosis Test

Review

If the HAPLOID number of an organism is 12, what would the diploid number be? 24

Gametes are produced by the process of Meiosis

The following is a picture of

Crossing over

Chromosomes form tetrads during Prophase 1

Crossing over occurs much more in meiosis than in mitosis. Which of the following is the likely reason?A. There are no tetrads with mitosis.B. There is no prophase with mitosis.C. There are no chromosomes

present.

The answer is A!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Meiosis results in #? (haploid / diploid) cells. 4 haploid

Mitosis results in #? ________ cells. 2 diploid

Mitosis goes through ___ division. 1

Meiosis goes through ___ divisions. 2

_______________ cells go through meiosis. Gametes (sperm, egg)

True or False: Liver, Nerve and Muscle cells DO NOT divide after maturity. TRUE

True or false In meiosis, all four daughter cells are genetically identical to the parent cell. FALSE

True or False You receive half of your chromosomes from mommy and half from daddy. TRUE

In what stage of meiosis does crossing over happen? Prophase 1

In what stage of meiosis do the sister chromatids separate? Anaphase 2

In what stage of meiosis do the homologous chromosomes line up in the middle? Metaphase 1

In what stage of meiosis do the sister chromatids line up in the middle? Metaphase 2

In what stage of meiosis do the homologous chromosomes separate? Anaphase 1

Why is meiosis important? Genetic Variety/diversity

Haploid means there are _?_ set(s) of chromosomes. 1(n)

Diploid means there are _?_ set(s) of chromosomes. 2(n)

Female sex chromosomes are homologous _?_ (letters that represent female) XX

Male sex chromosomes are homologous _?_ (letters that represent male) XY

46, 46, all others 23

What stage of mitosis?

Couldn’t get pictures on here so study your drawings paper. Also study your Venn Diagram and both Webquests (the ones I told you in class)
