The Phases of Meiosis

Question 1

chromosomes coil up and spindle the fibers form

Answer 1

Prophase I

Question 2

Homologous chromosomes come together forming a tetrad

Answer 2

Prophase I

Question 3

Crossing Over may occur when chromatids exchange genetic material resulting in new combinations of alleles on chromosomes

Answer 3

Prophase I

Question 4

The centromere of each chromosome becomes attached to a spindle fiber

Answer 4

Metaphase I

Question 5

The spindle fibers pull the tetards to the equator of the spindle

Answer 5

Metaphase I

Question 6

Homologous chromosomes separate and Mocs to opposite ends of the cell

Answer 6

Anaphase I

Question 7

Centromeres do not split-this ensures that each new cell will receive only one chromosome from each homologous pair

Answer 7

Anaphase I

Question 8

The spindle breaks down and the chromosome uncoil

Answer 8

Telophase I

Question 9

The cytoplasm divides to yield two new cells

Answer 9

Telophase I

Question 10

Each cell has half the genetic information of the original cell because it has only one homologous chromosome from each pair

Answer 10

Telophase I

Question 11

Chromosomes coil up and spindle fibers form

Answer 11

Prophase II

Question 12

Nucleoli and nuclear envelope disappear

Answer 12

Prophase II

Question 13

The chromosomes (each consisting of 2 chromatids) line up along the equator

Answer 13

Metaphase II

Question 14

The centromere of each chromosome splits

Answer 14

Anaphase II

Question 15

The sister chromatids separate and move to opposite poles

Answer 15

Anaphase II

Question 16

Nuclei reforms

Answer 16

Telophase II

Question 17

The spindle break down and the chromosomes uncoil

Answer 17

Telophase II

Question 18

The cytoplasm divides to yield four haploid sex cells

Answer 18

Telophase II

Question 19

The cell replicates it’s chromosomes each chromosome and has two sister chromatids held together by a centromere.

Answer 19

Interphase
