PROBLEM #1: ORANGE COLOR IS DOMINANT TO
YELLOW COLOR IN FRAGGLES. IF YOU CROSS A
HOMOZYGOUS DOMINANT ORANGE FRAGGLE
WITH A HOMOZYGOUS RECESSIVE YELLOW
FRAGGLE, WHAT WOULD BE THE KIDS’
GENOTYPES AND PHENOTYPES?
PROBLEM: YOU EVER WONDER WHY PAPA SMURF WAS
THE THE ONLY SMURF WITH FACIAL HAIR? THAT IS
BECAUSE FACIAL HAIR IS RECESSIVE IN SMURFS,
WHILE NO FACIAL HAIR IS DOMINANT. IF YOU CROSS
PAPA SMURF (HOMOZYGOUS RECESSIVE) WITH
SMURFET (HETEROZYGOUS), WHAT WOULD THE KIDS
LOOKS LIKE?

SCOOBY DOO HAS A RECESSIVE TRAIT, TALKING. MOST
DOGS CAN NOT TALK, WHICH IS DOMINANT. SCOOBY
MARRIES A NON-SPEAKING POODLE AND HAS THE
FOLLOWING OFFSPRING. WHAT WERE SCOOBY’S AND HIS
WIFE’S GENOTYPES?
T = NO TALK, t = TALKTt

Many science students have pondered why Barney the
Dinosaur is much smaller and more purple than a typical T-
Rex. DNA evidence has revealed that Green coloration (G) is
dominant to purple color (g) in T-rex’s. Also, large size (L) is
dominant to small size (l). If Barney’s genotype is ggll and
mates with another T-Rex that has the genotype GgLl,
describe the different possible offspring genotypes and
phenotypes (including their probabilities).
Clean up, clean
up. Everybody
everywhere.

PROBLEM: EVER WONDER WHY BIG BIRD IS SO BIG
AND TWEETY BIRD SO SMALL? LAVELLE
TECHNOLOGIES RESEARCHERS HAVE FOUND THAT
THEY ARE OF THE SAME SPECIES.
SHORTNESS (S) IS DOMINANT TO TALLNESS (s).
YELLOW COLOR (Y) IS DOMINANT TO ORANGE
COLOR (y).
CROSS BIG BIRD (ssYy) WITH TWEETY BIRD (SSYY).
DETERMINE THE POSSIBLE GENOTYPES AND
PHENOTYPES OF THE OFFSPRING.
Mr. Sponge Bob Squarepants ( a member of phylum Poriferaor sponges) has recently become engaged to Miss Jelly Jill Roundskirt ( a member of phylum Cnidaria or jellies). They went to a genetics counselor (you) to figure out if their kids will be sponges (hide your money!)(S) or jellyfish (s). Also, if they will have squarepants (P) or round skirts (p). They would like a genotype and phenotype ratio for each.
Bob is heterozygous for the sponge trait as well as for the type of garment. Jill is homozygous recessive for both traits.

The cookie monster married Zoe. The dominant trait C (uncontrollably
smashing cookies in one’s own mouth) is the opposite of c (uncontrollably
sniffing cookies). Also googly eyes G is dominant to non-googly eyes, g.
Given the following offspring, determine the parent genotypes, provided
that cookie monser is heterozygous for both.
