Red eyes (R) in fruit flies are dominant over white eyes (r).
What are the Genotype ratios for: Rr x rr r r R Rr Rr r rr rr
Rr = 2/4, rr=2/4
Red eyes (R) in fruit flies are dominant over white eyes (r).
What are the Phenotype ratios for Rr x rr?
2:2 2 Red eyes + 2 White
Red eyes (R) in fruit flies are dominant over white eyes (r).
What cross would result in a 50% chance of red eyes?
Rr x rr
Red eyes (R) in fruit flies are dominant over white eyes (r).
Is rR x Rr a possible cross? Explain.
Yes. The same gene is being crossed from each Gamete.
ALL play. First to hit button gives their team 2 minutes to answer. 500 Give Phenotype ratios for a dihybrid homozygous dominant cross with a heterozygous dominant cross. Use X and Y’s XY XY XY XY XXYY XY
100% Dominant

Category C 100 Left hand arm wrestle for points.
Female gets points if Male won.
Male gets double points if female wins.
Category C 200 •
Complete the heirarchy set of words: Kingdom, Phylum, Class . . .
Order, Family, Genus, Species
Category C 300 Is WwTt x TTRr a possible cross? And. . .
No. Both Gametes are not crossing the same genes.
Replace the Rr with Tr or vs/versa
Category C 400 Dance the robot for 10 seconds for points.
Other team: Teach the class a move from your favorite sport for 200pts
ALL play. First to hit button gives their team 1 minutes to answer. 500 Is RrDdLlS x DDLLsrr a possible combination? And . . .
No. Both gametes are missing the second allele for the S gene.
Category D 100 What will the phenotype be of a Gg organism.
G, whatever it is this time.
Category D 200 Will the recessive gene be a phenotype for an individual with Gg alleles for a given gene?
No because there is a dominant G that will express itself.
DAILY DOUBLE - Category D What is the Genus and species name for humans?
Homo Sapiens
Category D 400 Who is the father of Modern Taxonomy?
Carl Lenaeus
Category D 500 Who is the father of Modern Genetics?
Gregor Mendel
Category E 100 What is a Punnet square?
A chart used to find the ratio possibilities of genetic crosses.
Category E 200 Explain Phenotype!
The physical characteristics expressed by genes.
Category E 300 What are the Genotype ratios for a TtGG x ttgg?
TtGg=8/16 ttGg=8/16 50% chance of each.
Category E 400 What are the parent genotypes for gametes: BF BF bF bF and bF bf bF bf
BbFF x bbFf
ALL Play. First team to raise hand. Team only gets one chance. 500 In humans beings, brown eyes are usually dominant over blue eyes. If a brown-eyed man marries a blue-eyed woman and they have ten children, all brown-eyed, can you be certain that the man is homozygous? What is the only way you can be certain of the fathers genotype? EXPLAIN!
No. You cannot tell the genotype of the father no matter how many brown eyed children he has, BB
vs. Bb. Only if he has a blue eyed child can you determine for certain his genotype, Bb.
FINAL JEOPARDY!
brown-eyed and whose mother was
Bb X Bb Man Brown eyes Bb X bb blue eyed woman
brown eyed. The couple has a blue eyed
bb
woman's mother.
