Mitosis involves

PMAT I and II

Producing gametes

Producing haploid cells

Producing identical cells to parent cells

Category 1
category 11
Mitosis involves

Only Producing identical cells to parent cells

Category 1
category 13
How is Mitosis chromosome number different than Meiosis?

Mitosis is haploid- 1n

Meiosis is diploid – 2n

Category 1
category 14
What does not occur in prophase?

The nuclear envelope breaks up

Tetrads line up at the equator

30

Category 1
category 15
What does not occur in prophase?

Tetrads are in Meiosis I and they line up at the equator during metaphase

It produces 4 sperm cells

It produces 4 egg cells

10

Category 3
category 31
Which of these does not describe Meiosis?

It produces haploid cells

It produces 4 sperm cells

It produces 4 egg cells- It only produces 1 viable egg cell

Category 3
category 35
Describe Crossing Over and its affects.

the tips of chromosomes touch and exchange places on the same chromosome

It produces new DNA code in the cell

category 39
How is prophase 1 of meiosis different from prophase of mitosis?

Prophase has sister chromatids

Prophase I had Tetrads

50

Category 3
category 42
What is occurring?

Fertilization

Pollination

meiosis

20

Category 4
category 45
What phase is indicated?

Telophase or Telephase I

30

Category 4
category 47
What phase is indicated?

Anaphase or Anaphase I

40

Category 4
category 49
How can you tell the difference between the interphase and prophase?

Can see nucleolus and not see chromatids in interphase

50

Category 4
category 5
What is the difference between a homologous chromosome and a sister chromatid?

Homologous has 2 chromosome and sister chromatid has 4

Homologous are chromosomes with the same types of traits but are not identical, sister chromosomes are copies which are joined by a centromere.
