1. MEIOSIS SEXUAL REPRODUCTION

2. MEIOSIS & MITOSIS- slide 1

3. CHROMOSOMES : FACTS-slide 2 CHROMOSOMES CARRY GENETIC INFORMATION FROM PARENT TO OFFSPRING. EUKARYOTIC CHROMOSOME IS MADE OF DNA WRAPPED AROUND PROTEIN, A PROKARYOTIC CHROMOSOME IS A SINGLE CIRCLE OF DNA. BEFORE EUKARYOTIC CELL DIVIDES, A CHROMOSOME CONDENSES INTO A COMPACT ROD-SHAPED BODY THAT CAN EASILY MOVE AROUND THE CELL.

4. CHROMOSOMES: slide 4

5. MEIOSIS: slide 5 IN SEXUAL REPRODUCTION – MEIOSIS THE NUMBER OF CHROMOSOMES ARE REDUCED FROM THE DIPLOID NUMBER (2N) ____TO THE HAPLOID NUMBER (1N) _____. A GAMETE IS A HAPLOID REPRODUCTIVE (SEX) CELL- EGG (OVUM) OR SPERM.

6. CROSSING OVER- HOW GENETIC INFORMATION FROM EACH PARENT IS TRANSFERRED TO THEIR OFFSPRING: slide 6

7. CROSSING OVER: slide 7 CROSSING-OVER IS THE EXCHANGE OF SEGMENTS OF DNA BETWEEN HOMOLOGOUS (SAME/ALIKE) CHROMOSOMES. IT IS A SOURCE OF GENETIC VARIATION. MUTATIONS IN THE SEX CELLS CAN BE PASSED ON FROM PARENTS TO OFFSPRING.
