Sex cellls

• Gametes

• Somatic

• Mieosis 1

• Meiosis 2

is the production of sex cells with haploid chromosomes

• Meiosis

• Mitosis

• Passive transport

• Carrier proteins

Nucleolus and the nuclear membrane starts to disintegrate.

• Prophase 1

• Prophase 2

• Anaphase 2

• Metaphase 1

Pairing of homologous chromosomes called synapsis. Two homologous chromosomes come from maternal and paternal genetic material.

• Prophase 2

• Prophase 1

• Anaphase 2

• Telophase 1

the term for four sister chromatids from the pair of chromosomes that are visible during prophase.

• Tetrad

• Petra

• Synapsis

• Tetra

Crossing-over between non-sister chromatids occurs during this stage.

• Metaphase 1

• Prophase 2

• Prophase 1

• Telophase 2

happens when portions of a chromatid on one homologous chromosome breaks, exchanges, and rejoins genetic material with corresponding portions on one of the chromatids of other homologous chromosome.

• Crossing over

• Tetrad

• Jumpshot

• Meiosis 2

is the point of crossing over, resulting in genetic variability of sex cells

• Chiasmata

• Tetrad

• Mitosis 1

• Synapsis

Centrosomes move at the opposite poles

Spindle fibers form.

• Prophase 1

• Metaphase 1

• Prophase 2

• Anaphase 2
