Answer 5

Haploid

Question 6

Meiosis has ______ phases

Answer 6

2

Question 7

Prophase 1: Each replicated chromosome pairs with its corresponding homologous forming a __________

Answer 7

tetrad

Question 8

During tetrad formation alleles can be exchanged between chromatids. A process called _____________

Answer 8

crossing over

Question 9

Paired homologous chromosomes line up across the center of the cell

Answer 9

Metaphase 1

Question 10

Spindle fibers pull each homologous pair toward opposite ends of the cell

Answer 10

Anaphase 1

Question 11

A nuclear membrane forms around each cluster of chromosomes. Cytokinesis then occurs, resulting in two new cells. The resulting daughter cells contain chromosome sets that are different from each other and parent cell.
