1. MITOSIS AND MEIOSIS QUICK REVIEW

2. WHICH KINDS OF CELLS ARE DIPLOID? Somatic or Body Cells

3. HOW MANY DAUGHTER CELLS ARE AT PRODUCED AT THE END OF MITOSIS? Two Cells

4. HOW MANY CHROMOSOMES ARE IN EACH DAUGHTER CELL AT THE END OF MITOSIS? 46 chromosomes

5. A ______ IS CREATED WHEN A SPERM ENTERS AN EGG zygote

6. THE EXCHANGE OF GENETIC MATERIAL THAT OCCURS DURING PROPHASE I OF MEIOSIS IS CALLED _______ Crossing- Over

7. THE HIGHER THE CHROMOSOME NUMBER, THE MORE COMPLEX AN ORGANISM IS: TRUE OR FALSE False

8. ANOTHER NAME OF A CELL THAT CAN BE REPRESENTED BY N OR 1N IS KNOWN AS A ________ CELL Haploid

9. DURING MEIOSIS, DNA WILL REPLICATE BEFORE THE FIRST DIVISION OF MEIOSIS AND BEFORE THE SECOND DIVISION OF MEIOSIS: TRUE OR FALSE FALSE: It will only replicate before the first division! If it replicates before both divisions the chromosome number will never be cut in half.
