BREED FAMILY MEMBERS WITH EACH OTHER.
11. TRUE OF FALSE: A PUNNETT SQUARE SHOWS THAT TWO ORGANISMS
WILL PRODUCE 4 BABIES.
12. TRUE OF FALSE: ACQUIRED TRAITS ARE THOSE THAT YOU GET FROM
YOUR FAMILY.
DO PUNNETT SQUARES FOR THE FOLLOWING:
13. DD x dd
14. Rr x rr

WORD PROBLEMS: SHOW ALL WORK!!
17. CROSS A HOMOZYGOUS DOMINANT WHITE CAT WITH A HOMOZYGOUS
RECESSIVE BLACK CAT. (DO PHENOTYPE AND GENOTYPE)
100% HETEROZYGOUS
100% WHITE CATS
18. CROSS A HETEROZYGOUS BROWN COW WITH A HOMOZYGOUS RECESSIVE TAN
COW. (DO PHENOTYPE AND GENOTYPE)
50% HETEROZYGOUS
50% HOMOZYGOUS RECESSIVE
50%BROWN
50%TAN
19. EXPLAIN WHY MALES (XY) ARE MORE LIKELY THAN FEMALES (XX) TO GET SEXLINKED DISEASES.
MALES ONLY HAVE ONE COPY OF THE X CHROMOSOME. MOST SEX-LINKED
DISEASES ARE ON THE X CHROMOSOME, SO THE MALE DOES NOT A CHANCE AT
GETTING ANOTHER X CHROMOSOME TO COVER OVER THE ONE WITH THE
DISEASE.
20. EXPLAIN WHAT A PEDIGREE IS USED FOR AND WHAT ALL OF THE SHAPES
REPRESENT. WHY IS IT A USEFUL TOOL?
CIRCLE-FEMALES
SQUARE-MALES
LINES BETWEEN CIRCLE/SQUARE-MEAN A MARRIAGE
HALF SHADED-MEANS THEY ARE A CARRIER

WHAT WOULD THEIR BLOOD PHENOTYPE BE?
A,B,O
AO-A PHENOTYPE
22. WHAT IS INCOMPLETE DOMINANCE?
WHEN NEITHER ALLELE WANTS TO DOMINATE OVER THE OTHER. THE RESULT IS
A BLENDING OF TRAITS
23. HOW SHOULD BIOTECHNOLOGY BE USED, IF AT ALL?
OPINION
24. WHAT IS PROBABILITY AND HOW IS IT USED IN GENETICS?
IT IS A BRANCE OF SCIENCE/MATH USED TO PREDICT OUTCOMES
PROBABILITY IS USED TO MAKE PREDICTIONS ABOUT WHAT WILL HAPPEN WHEN
TRAITS GET PASSED ON.
25. LIST THE DISEASES/DISORDERS THAT SCIENTISTS WERE STUDYING IN DOGS, IN
HOPES TO HELP PEOPLE WHO HAVE THOSE DISEASES/DISORDERS. FOR WHICH
DISEASE DID THEY FIND THE GENE THAT CAUSES IT?
SOCIAL DISORDERS-AUTISM/SCHIZOPHRENIA
NARCOLEPSY-FOUND THE GENE FOR THIS ONE
