BELLWORK 2-13-15CREATE A PUNNETT SQUARE

SCENARIO TO SHARE WITH THE CLASS. WE WILL SHARE THESE

WITH THE CLASS AND WORK THEM OUT TOGETHER.

TURN IN CELEBRITY GENETICS

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.
