If AaBb is crossed with aabb, what proportion of the offspring would be
expected to be aabb?
If the offspring of a cross show a 9/16 to 3/16 to 3/16 to 1/16 ratio
(9:3:3:1), the parents of the cross have the genotypes
AaBb x AaBb
b. AaBb x aaBB
c. aaBb x aabb
d. aaBb x Aabb
Whenever a capital letter is present, a red color is produced. In a cross of
AaBb x AaBb, how many red offspring would you expect out of 16?
Assume that you mated two individuals heterozygous for each of two traits and
obtained 80 offspring. How many of them would be expected to look like their
Genes that assort independently are

located on the same chromosome
c. alleles of
If W = purple flower and w = white, and D = tall plants and d = short plants,
a wwDd plant would be
purple and tall
b. purple and short
c. white and tall
d. white and short
If two true-breeding parents are crossed with each other and all the offspring
have their mother's ears and their father's tail, the parents in the cross
EETT x eett
b. eeTT x EEtt
c. EeTt x EeTt
d. eeTt x Eett
If aaBb is crossed with AAbb, what proportion of the offspring will be AAbb?
If AaBb is crossed with AaBb, what proportion of the offspring will be
dominant for the 'A/a' trait and recessive for the 'B/b' trait (i.e. A-bb)?
