Meiosis

Question 1

Mitosis vs meiosis

Answer 1

Mitosis diploid - 2diploid(identical)
Miosis - diploid - 4 haploid cells (not identical)

Question 2

Interphase parts

Answer 2

G1- cell growth recover and regular cell functions
S - trigger send cell into s phase where dna synthesis or replication occurs
G2- trigger sends into g2 to prep for division - make spindle fibers and make centrioles and spindle fibers and extra organelles.

Question 3

Mitosis prophase

Answer 3

Nuclear envelope disappears

Question 4

Metaphase mitosis

Answer 4

Line up sister chromosomes on line

Question 5

Anaphase mitosis

Answer 5

Seperate sister chromosomes
And split the apart begin to drag them

Question 6

Telophase

Answer 6

Start to reform nuclear membrane and cell membrane begins to divide

Question 7

Where does genetic diversity take place in meiosis

Answer 7

Prophase 1 - crossover
Metaphase 1 - random assortment
Random fertilization afterwords

Question 8

Telomere

Answer 8

Tip of the chromosome
Protective helmet

Question 9

Centromeric región

Answer 9

Center
Where the he kinetochore protien can lach on top to help pull it apart

Question 10

Sister chromatides

Answer 10

Duplicated chromosomes
One side is a chromitid

Question 11

Homogeneous chromosomes

Answer 11

2 of the same chromosomes but from different parents

Question 12

Crossing over

Answer 12

Metaphase 1
Tetrad forms with 2 sister chromotids / 4 chromoitids come together

Synaptonemal complex: protien clonolex that’s holds the chromosomes together

Chiasma is where the crossing over actually occurs

Synapses ( all of it sort of together)

Question 13

Random assortment

Answer 13

Metaphase 1
Randomly putting chromosomes on sides
There are 8 million different possibilities
Ex

Dad mom
Dad mom

Mom dad
Dad. Mom

Question 14

Metaphase 1

Answer 14

Only homologous chromosomes lined up

Question 15

Metaphase 2

Answer 15

Only sister chromatids line up

Question 16

Human (animals)

Answer 16

Diploid dominant

2 haploids come together through fertilization and make a a zygote

The zygote goes through mitosis to become an adult

Adult goes through meiosis to make more gametes haploid cells

Question 17

Haploid dominant

Answer 17

Fungí

Zygote goes through meiosis to become multi cell which then goes through mitosis to make new haploids (spores) which then form a new zygospores

Question 18

Plants

Answer 18

= diploid /haploid

Haploid egg and polen fuse and become a zygote seed

They go through mitosis to become a multicellular adult

Go through meiosis to make haploid spores (which become multicellular adults through mitosis again) and also to make new gametes because they already haploid
