In wild cats, long tails (L) are dominant to bobtails (l). Which genotype(s) give a long-tailed cat? LL ll Ll In Aardvarks, straight hair (S) is dominant to curly hair (s). Two heterozygous Aardvarks (male and female) mate and produce four beautiful offspring. Fill in the Punnet Square below with the correct genotypes of the offspring from this cross. Ss X Ss Set up the Punnett Square for the monohybrid cross that is listed below. The trait being studied is round seeds (dominant) and wrinkled seeds (recessive). Rrx rr In Smileys, eye shape can be starred (SS), circular (CC), or a circle with a star (CS). CC SS CS Imagine a cross between a circle eyed and a circle-star eyed. CC x CS What percentage of the offspring will be circle eyed? What percentage of the offspring will be circle-star-eyed? What percentage of the offspring will be starred eyed?

Imagine a cross between a circle eyed and a circle-star eyed. CC x CS
What percentage of the offspring will be circle eyed?
What percentage of the offspring will be circle-star-eyed?
What percentage of the offspring will be starred eyed?
In humans, the four blood types A, B, O, and AB are determined by three alleles IA, IB, and i.
Write the genotype for each person based on the descriptions given below:
a. Homozygous for the “B” allele
b. Heterozygous for the “A” allele
c. Type O
d. Type “A” and had a type “O” parent
e. Type “AB”
f. Blood can be donated to anybody
g. Can only get blood from a type “O” donor
Mrs. Essy is type “A” and Mr. Essy is type “O.” They have three children named Matthew, Mark, and Luke. Mark is type “O,” Matthew is type “A,” and Luke is type “AB.” Based on this information:
a. Mr. Essy must have the genotype
b. Mrs. Essy must have the genotype because has blood type
c. Luke cannot be the child of these parents because neither parent has the allele
In garden peas, round seeds (R) are completely dominant to wrinkled seeds (r), and yellow seeds (Y) are completely dominant to green seeds (y). Consider the following dihybrid cross.
Answer the following questions based on the results of this cross shown in the image above.
How many of the offspring are yellow and round?
How many of the offspring are green and wrinkled?
How many of the offspring are yellow and wrinkled?
How many of the offspring are green and round?
How many different
How many different genotypes are possible in the offspring?
