Meosis

Front 1

Prophase 1

Back 1

• Chromosomes that are duplicated in interphase 1 remain sister chromatids
• Homologous chromosomes join and form pairs
• Membrane surrounding nucleus breaks apart

Front 2

Metaphase 1

Back 2

• Homologous chromosome pairs align along the middle of the cell
• Spindle fibers attach to each pair

Front 3

Anaphase 1

Back 3

• Pairs of duplicated homologous chromosomes separate and are pulled toward opposite ends of the cell
• Sister chromatids stay together

Front 4

Telophase 1

Back 4

• Nuclear membrane forms around each group of chromosomes
• Cytoplasm divides forming 2 daughter cells
• Sister chromatids stay together

Front 5

Prophase 2

Back 5

• Chromosomes do not duplicate
• Nuclear membrane breaks apart

Front 6

Metaphase 2

Back 6

Sister chromatids align along the middle of the cell

Front 7

Anaphase 2

Back 7

Sister chromatids of each duplicated chromosome are pulled apart and move to opposite sides of the cell

Front 8

Telophase 2

Back 8

• Nuclear membrane forms around each set of chromatids which are again called chromosomes
• Cytoplasm divides and 4 cells form
• Each cell has half the number of chromosomes as the original cell

Front 11

fertilization

Back 11

process where an egg cell and sperm cell join together

Front 12

zygote

Back 12

cell formed after fertilization

Front 13

homologous

Back 13

pairs of chromosomes that have genes for the same traits arranged in the same order

Front 14

sister chromatid

Back 14

separate to produce 4 haploid cells

Front 15

meosis

Back 15

the division of a reproductive cell & its nucleus that produces 2 pairs of identical haploid cells

Front 16

offspring

Back 16

• produced after sexual reproduction
• has a new combination of DNA

Front 17

Back 18

male sex cell
