WHAT DOES MEIOSIS CREATE?

• CHROMOSOMES

• GAMETES

• DNA

• TRAITS

MEIOSIS IS NEEDED BECAUSE...

• IT ACTUALLY ISN'T, BUT CAN BE HELPFUL IN SOME ORGANISMS

• TO REDUCE THE CHROMOSOME NUMBER BY HALF

• SO THAT EVERY CELL IS EXACTLY IDENTICAL

• TO MAKE SURE EVERY HUMAN CELL HAS 92 CHROMOSOMES

THE END RESULT OF MEIOSIS IS...

• FOUR UNIDENTICAL GAMETES

• FOUR IDENTICAL GAMETES

• TWO IDENTICAL GAMETES

• TWO UNIDENTICAL GAMETES

CROSSING OVER ALLOWS FOR WHAT TO HAPPEN?

• ALL CELLS TO STAY THE SAME

• GENETIC VARIATION

• REDUCTION OF CHROMOSOMES

• CHROMOSOME NUMBER TO INCREASE

THIS IMAGE SHOWS WHAT IS HAPPENING WITH THE CHROMOSOMES?

• NON- DISJUNCTION

• METAPHASE

• TELOPHASE

• CROSSING OVER
