Question

Will give a medal
1. Draw a tetrad in the space below and label the following: centromeres, sister chromatids, homologous chromosomes

2. What are the two elements of meiosis that add variation to our population? (Hint: one occurs in prophase I and the other in metaphase 1 (not anaphase 2).


1. Name 2 differences between mitosis and meiosis.
2. Does mitosis more closely resemble meiosis I or meiosis II? Explain your answer.
3. What is crossing over? When does it occur during meiosis? Why did you have difficulty modeling this element of meiosis using your “chromosomes?”

Answer 1

4.Visually, what is the major difference between the separation of chromosomes between anaphase I and anaphase II

Answer 2

5. What is independent assortment? When does it occur during meiosis? How did you model this element of meiosis?

6. Which part of meiosis, meiosis I or meiosis II, is responsible for reducing the chromosome number by half in the cell?

Answer 3

answer for number four is what I find remarkable about anaphase I and II is that in the former the centromere remains unsplit and in the latter the centromere is split resulting in separation of sister chromatids.

Answer 4

okay.. do u know any others

Answer 5

number 1 is this picture

Answer 6

okay

Answer 7

number 2 the two elements of meiosis are independent assortment and genetic recombination.

Answer 8

thanks.

Answer 9

@madison_none

Answer 10

the two differences between mitosis and meiosis are mitosis is for body cells while meiosis is for sex cells, meiosis creates 4 daughter cells unlike mitosis which only creates 2

Answer 11

okay so i just need 2 3 5 6

Answer 12

meiosis II because haploid cells are formed, which is what happens in mitosis.

Answer 13

thanks lots.. so 3 5 and 6

Answer 14

1. Crossing over is when two chromosomes exchange their genetic materials in a process called synapsis.
2. It occurs in meiosis 1 during prophase 1.
3. One example: Your chromosomes may end up crossing over with wrong chromosomes due to mutation in one of the chromosome or both.

Answer 15

1.2.and3..? thoes were already answered exept for 3....../??

Answer 16

no this the answer to question three

Answer 17

oh okay

Answer 18

i'm sorry i can't find number five in my book but i can answer six for you the answer to six is that meiosis 2 is responsible for reducing the chromosome number in half

Answer 19

thanks you helped so much.

Answer 20

your welcome and if you ever need more help just ask
