Meiosis & Genetics

Question 1

What is Meiosis?

Answer 1

A type of cell division that reduces the number of chromosomes in a cell and produces gametes

Question 2

What is a Haploid?

Answer 2

A cell with n chromosomes

Question 3

What is a Diploid?

Answer 3

A cell that contains 2n chromosomes

Question 4

What is Interphase?

Answer 4

When two chromosomes replicate and chromatin condenses

Question 5

What are Gametes?

Answer 5

Sex cells with half the number of chromosomes

Question 6

What are traits?

Answer 6

Characteristics such as hair color, eye color, etc

Question 7

What are Genes?

Answer 7

DNA segments that control the production of a protein

Question 8

What are homologous chromosomes?

Answer 8

The chromosomes that make up a pair

Question 9

What do chromosomes contain hundreds of?

Answer 9

Genes

Question 10

What do gametes end up with different combinations of?

Answer 10

Chromosomes

Question 11

Why is Meiosis important?

Answer 11

It provides variation

Question 12

What happens during Prophase I?

Answer 12

Pairing of homologous chromosomes occurs

Question 13

What happens during Telophase I?

Answer 13

Chromosomes reach the cell’s opposite poles

Question 14

What is Anaphase I?

Answer 14

When Homologous chromosomes separate and move to opposite poles of the cell

Question 15

What is Metophase I?

Answer 15

When Chromosome centromeres attach to spindle fibers

Question 16

What is Prophase II?

Answer 16

When a second set of phases begins as the spindle apparatus forms and the chromosomes condense

Question 17

What is Metophase II?

Answer 17

When Chromosomes are positioned at the equator

Question 18

What is Anaphase II?

Answer 18

When sister chromatids are pulled apart at the centromere by spindle fibers and move toward the opposite poles of the cell

Question 19

What is Telophase II?

Answer 19

When the chromosomes reach the poles and the nuclear membrane and nuclei form.
