Question 3

What happens in s-phase

Answer 3

DNA replication

Question 4

What is cancer

Answer 4

Uncontrolled cell growth

Question 5

Prophase 1

Answer 5

Chromosomes pair up to for tetrad, cross over occurs, Diploid

Question 6

Metaphase 1

Answer 6

Pairs of chromosomes line up in middle, independent assortment occurs, diploid.

Question 7

Independent Assortment

Answer 7

Chromosomes share information with one another

Question 8

Anaphase 1

Answer 8

Spindle fibers pull homolgous chromosome pairs towards the end of the cell, the tetred are gone, diploid.

Question 9

Telophase 1

Answer 9

Memebraine forms around each cluster of chromosomes, dipoid.

Question 10

At what point do the cells become haploid.

Answer 10

After telophase 1 and during cytokinesis.

Question 11

Prophase 2

Answer 11

Chromosomes woth sister chromatids, hapliod.

Question 12

Anaphase 2

Answer 12

Sister chromatids are pulled towards opposites ends of cell, hapliod

Question 13

Telophase 2

Answer 13

Membrane forms around each group of chromosomes, hapliod.

Question 14

Fertilization

Answer 14

when egg cell fuses with sperm cell

Question 15

What are three sexual sources of genetic variation

Answer 15

• Crossing over, Independant Assortment, Random fertilization.

Question 16

Tetrad

Answer 16

A pair of homologous chromosomes that move as a unit

Question 17

Gametes

Answer 17

Haploid sex cells produced by meiosis

Question 18

Zygote

Answer 18

Fertilized egg that undergoes mitosis to form baby.
