Correct. The male and female are both Tt. So, there
is a 75% chance that the child will receive at least
one T allele.

many chromosomes do gametes have?

Question 8

Red (R) flower color is incompletely dominant to
white (r) flower color. Which cross will produce
100% pink flowers?
Question 9
Points: 10 out of 10
An individual that expresses the recessive trait of a
dominant/recessive gene
E must be homozygous
F must be heterozygous
G can be either homozygous or heterozygous
Feedback
Correct. Only aa will result in the expression of the
recessive trait.
Question 10

Points: 0 out of 10
In humans, there are 3 alleles for blood type: A, B,
O. A and B are co-dominant over O. A male with O
type blood mates with a female with AB type blood.
What is the chance that their child will be type A?
E 0%
F 75%
G 100%
H 25%
I 50%
Feedback
Incorrect. OO x AB produces 50% AO (type A) and
50% BO (type B).

Question 14
Points: 10 out of 10
What would be the result of fertilization if egg and
sperm were produced by mitosis rather than
meiosis?
E The resulting offspring would have twice as much
DNA as the parents.
F The resulting offspring would have half the amount
of DNA as the parents.
G The resulting offspring would have the same amount
of DNA as the parents.
Feedback
Correct. Mitosis produces diploid cells. If a diploid
egg and a diploid sperm fused, the resulting cell
would be tetraploid.
