Meiosis

What causes genetic variation in meiosis?

• chromosomes lining up

• crossing over of chromosomes

• separation of chromosomes

• chromosomes pulling apart

What kind of cells are made in MEIOSIS?

• Haploid cells

• Diploid Cells

• Skin Cells

• Liver Cells

Diploid Cells are represented by

• 2n

• n

• 4n

• 1/2 n

If the Diploid number of Carrots is 18, the haploid number is

• 18

• 9

• 27

• 36

The process of crossing over occurs in what phase of meiosis?

• anaphase 1

• prophase 1

• prophase 2

• telophase 1

The chromosomes that pair up during meiosis, are called __________ chromosomes.  

• homozygous 

• asexual

• homologous

• genes

When homologous chromosomes match up, they form a structure call a ___________.

• tetrad (pair of chromosomes, one from mom and one from dad)

• triad

• diploid

• quad (group of 4 replicated chromosomes, 2 from mom and 2 from dad)

Crossing over creates

• male genotype

• genetic variation (differences)

• DNA replication

• mitosis

Which cellular process is shown?

• meiosis

• endocytosis

• mitosis

• phagocytosis

Which of the following best describes meiosis?

• It is carried out in all tissues theat require cell replacement

• It occurs only in cells in the reproductive structures of an organism

• It happens in all of the tissues except the brain and spinal cord

• It is the first stage of mitosis
