MEIOSIS REVIEW

Page 2: Meiosis Review

Gametes

________ are sex cells.

Page 3: Meiosis Review

Haploid

The daughter cells produced at the end of meiosis II are

considered- diploid or haploid?

Page 4: Meiosis Review

Genetically DIFFERENT!

What is the genetic relationship of daughter cells

to each other in meiosis?

Page 5: Meiosis Review

4

How many daughter cells are produced from

meiosis?

Page 6: Meiosis Review

Egg cell

_______ is the female gamete.

Page 7: Meiosis Review

Homologous chromosomes

___________ are the paired chromosomes that have genes for the same traits arranged in

the same order.

Page 8: Meiosis Review

Fertilization

_________ is the process of joining gametes.

Page 9: Meiosis Review

XY

What are the male sex chromosomes?

Page 10: Meiosis Review

46

How many chromosomes do you have in your skin

cells?

Page 11: Meiosis Review

Diploid

____________ is a cell containing 2 sets of

chromosomes.

Page 12: Meiosis Review

NO!A dog has 78 chromosomes and is less complex than humans

Is the number of chromosomes related to the complexity of an

organism? WHY?

Page 13: Meiosis Review

Meiosis

_______ is a two stage type of cell division that creates gametes.

Page 14: Meiosis Review

23

At the end of meiosis II, how many (human) chromosomes

does each daughter cell have?

Page 15: Meiosis Review

1

How many cell divisions occur in MITOSIS?

Page 16: Meiosis Review

Diploid

The daughter cells produced at the end of MITOSIS are

considered- haploid or diploid?

Page 17: Meiosis Review

46

What is the diploid number in humans?

Page 18: Meiosis Review

Somatic cells

__________ are all cells other than egg or sperm cells.

Page 19: Meiosis Review

23

How many chromosomes do you have in your egg

or sperm cells?

Page 20: Meiosis Review

Genetically the SAME!

What is the genetic relationship of daughter cells

to each other in MITOSIS?

Page 21: Meiosis Review

zygote

________ is the cell that is created when a sperm

fertilizes an egg.

Page 22: Meiosis Review

XX

What are the female sex chromosomes?

Page 23: Meiosis Review

Genetically DIFFERENT!

What is the genetic relationship of daughter cells

to parent cell in meiosis?

Page 24: Meiosis Review

Haploid

_________ is a cell with only ONE set of chromosomes.

Page 25: Meiosis Review

1. creates haploid gametes2. provides genetic variation

Why is meiosis significant? (2 reasons)

Page 26: Meiosis Review

23Homologous Chromosomes

How many chromosomes do you get from your

mom?

Page 27: Meiosis Review

Prophase I

During what stage of meiosis does crossing

over occur?

Page 28: Meiosis Review

2

How many cell divisions occur in meiosis?

Page 29: Meiosis Review

Crossing over

__________ occurs when nonsister chromatids of

homologous chromosome exchange genetic information.

Page 30: Meiosis Review

Genetically the SAME!

What is the genetic relationship of daughter cells

to parent cell in MITOSIS?

Page 31: Meiosis Review

46

At the end of meiosis I, how many (human) chromosomes

does each daughter cell have?

Page 32: Meiosis Review

1. Crossing over – random swapping of DNA

2. Independent assortment of the homologous chromosomes – it is random to which side of the cell the chromosomes move to

EXPLAIN how meiosis provides genetic

variation? (2 ways)

Page 33: Meiosis Review

2

How many daughter cells are produced from

MITOSIS?

Page 34: Meiosis Review

23

What is the haploid number in humans?

Page 35: Meiosis Review

Haploid

Are your sex cells diploid or haploid?

Page 36: Meiosis Review

Diploid

Are your somatic cells diploid or haploid?

Page 37: Meiosis Review

sperm

______ is the male gamete.
