1. BELLWORK 2-13-15 CREATE A PUNNETT SQUARE SCENARIO TO SHARE WITH THE CLASS. WE WILL SHARE THESE WITH THE CLASS AND WORK THEM OUT TOGETHER.

2. TURN IN CELEBRITY GENETICS

3. TO ANSWER A FEW QUESTIONS... INCOMPLETE DOMINANCE (LETS READ PG. 110!)- SOME TRAITS ARE NOT COMPLETELY DOMINANT OVER OTHERS. THEY DON'T BLEND BUT EACH TRAIT HAS IT'S OWN DEGREE OF INFLUENCE. HOW DO TWINS WORK? IDENTICAL TWINS ARE WHEN ONE SPERM FERTILIZES ONE EGG, AND THEY SEPARATE INTO TWO BABIES. IDENTICAL TWINS HAVE THE SAME SETS OF DNA. FRATERNAL TWINS ARE WHEN TWO DIFFERENT SPERM FERTILIZE TWO DIFFERENT EGGS. FRATERNAL TWINS DO NOT HAVE THE SAME SETS OF DNA. THEY ARE NO MORE ALIKE THAN SIBLINGS WHO ARE BORN SEVERAL YEARS APART.

4. TO SUM UP! AMOEBA SISTERS PUNNETT SQUARES VIDEO

Interphase, prophase, metaphase, anaphase, telophase, cytokinesis 28. a structure in the nucleus made of DNA and proteins 29. chromosomes that have the same structure and similar genes 30. Cell Cycle 31. Mitosis- creates new body cells, IPMAC, two new cells are formed that are identical to parent cell; Meiosis- creates sex cells, IPMAC, IPMAC II, four new cells are formed with half the number of chromosomes 32. Bacterium- Asexual, hydra-asexual, strawberry-Asexual and jellyfish sexual 33. binary fission 34. budding 35. fragmentation 36. regeneration 37. Punnett Square 38. Phenotype 39. Genotype
