• Question 1
30 seconds
Q. Both parents in this Punnet square
are homozygous dominant
are homozygous recessive
are heterozygous
have blue eyes
• Question 2
30 seconds
Q. Axial flowers is dominant to terminal. What is the probabilty of offspring being terminal?
1/4
2/4
3/4
4/4
• Question 3
30 seconds
Q. The genotypic ratio here is
25% blue eye 75 % brown eye
BB = 25% Bb = 50% bb = 25%
BB= 50 % bb = 50%
All brown eye
• Question 4
30 seconds
Q. How many boxes would say BB?
1
2
4
0
• Question 5
30 seconds
Q.

Brown is dominant to green. What is the probability of these parents having green offspring?

1/4

2/4

3/4

4/4

• Question 6
30 seconds
Q. What is the genotypic ratio here
TT = 25% Tt= 50% tt=25%
all tall
TT= 75% tt = 25%
Tt = 100%
• Question 7
30 seconds
Q. The dominant trait is
yellow pea seeds
green pea seeds
there is no dominant seed
Jolly green giant
• Question 8
30 seconds
Q. To be a yellow seed genotype must be
aa
Aa
AA
AA or Aa
• Question 9
30 seconds
Q. To express the recessive trait you must be
homozygous dominant
heterozygous
alleleerific
homozygous recessive
• Question 10
30 seconds
Q. A Punnet Square will
tell you exactly what your offspring will look like
increase the chance you pass on recessive traits
predict genotypes and phenotypes in offspring
have no purpose but for Taylor to give us extra assignments
• Question 11
30 seconds
Q. How do two purple flowers produce white flower offspring?
