Module 14

Question 1

Anaphase I

Answer 1

Homologous chromosomes separate and move to opposite end of the poles

Question 2

Gamete

Answer 2

A haploid sex cell that undergoes meiosis when two gametes join in fertilization.

Question 3

Metaphase I

Answer 3

Homologous chromosome pairs are attached to the fully formed spindle.

Question 4

Sexual reproduction

Answer 4

Sperm and egg make a diploid zygote.

Question 5

Anaphase II

Answer 5

The centromeres separate and the sister chromatids move forward to the other end of the pole

Question 6

Haploid

Answer 6

Only one set of chromosomes. Gametes are haploid.

Question 7

Metaphase II

Answer 7

Chromosomes line the equator of the cell and are attached to the fully formed spindle

Question 8

Telophase I

Answer 8

The end stage, homologous pair reach the poles of the cell nuclear envelopes from around the and produce two separate cells

Question 9

Asexual reproduction

Answer 9

Bacteria and fungi are examples.

Question 10

Meiosis I

Answer 10

First half of the whole process. Homologous pairs of chromosomes bind together and cross over

Question 11

Prophase I

Answer 11

First stage chromosomes condense and become visible, crossing over occurs, the nucleus disappears,the spindles form and nuclear envelope disappears

Question 12

Telophase II

Answer 12

Produces 4 daughter cells with a haploid set of chromosomes

Question 13

Diploid

Answer 13

Contains two sets of chromosomes. One set is inherited from mother and other from father. Diploid cells are 2n. Somatic and germ cells are diploid

Question 14

Meiosis II

Answer 14

Production of four haploid gamete cells and is similar to mitosis

Question 15

Prophase II

Answer 15

The nuclear envelope breaks down and spindle forms
