Exercise 3

Question 1

what are the 4 stages of meiosis 1?

Answer 1

prophase 1, metaphase 1, anaphase 1, and telophase 1.

Question 2

what is meiosis?

Answer 2

the processes that separates homologous chromosomes into different daughter cells, which results in the reduction of chromosomes by half.

Question 3

what happens during prophase 1?

Answer 3

chromosomes condense, crossing over occurs, spindle apparatus, and the nuclear envelope breaks apart.

Question 4

what happens during metaphase 1?

Answer 4

homologous pairs of chromosomes align along the central “equator” of the cell.

Question 5

what happens during anaphase 1?

Answer 5

spindle apparatus separates the homologous chromosomes and pulls each chromosomes to opposite poles.

Question 6

what happens during telophase 1?

Answer 6

spindle apparatus detaches, nuclear envelope reforms, chromosomes decondense, and cytokinesis occurs.

Question 7

what are the 4 stages of meiosis 2?

Answer 7

prophase 2, metaphase 2, anaphase 2, and telophase 2.

Question 8

what happens during prophase 2?

Answer 8

chromosomes condense, spindle apparatus forms, nuclear envelope breaks apart. (same as prophase 1)

Question 9

what happens during metaphase 2?

Answer 9

chromosomes align along the central “equator” of the cell (same as metaphase 1). The sister chromatids are still attached and the chromosomes remain duplicated.

Question 10

what happens during anaphase 2?

Answer 10

spindle apparatus separates the sister chromatids and pulls each one to opposite poles (same as anaphase 1). now the chromosomes are unduplicated.

Question 11

what happens during telophase 2?

Answer 11

spindle apparatus detaches, nuclear envelope reforms, chromosomes decondense, and cytokinesis occurs (all the same as telophase 1). There are now a total of 4 cells will half the total number of chromosomes.

Question 12

what is the locus?

Answer 12

the position where each gene is found.
