Punnett Square – 100
A four-sided tool used for predicting traits
Punnett Square
Punnett Square- 200
What’s the first step in solving the following problem?
If you cross a homozygous dominant purple pea plant with a heterozygous pea plant, what’s the probability of the
offspring being purple?
underline the important information
Punnett Square 300
After underlining, what’s the next step in solving the following problem?
If you cross a homozygous dominant purple pea plant with a heterozygous pea plant, what’s the probability of the offspring being purple?
Figure out what is dominant and what is recessive
Punnett Square 400
After figuring out what’s dominant and recessive, what’s the next step for solving the problem of:
If you cross a homozygous dominant purple pea plant with a heterozygous pea plant, what’s the probability of the offspring being purple?
Labeling for mom and dad or plant 1 or plant 2, etc.
Punnett Square- 500
What’s the last step before making the cross to complete a Punnett Square?
Place alleles (genotypes) on the top and side of the square

_______gous – 100
Two alike alleles are known as
homozygous
_______gous - 200
A genotype with different alleles is known as
Heterozygous
______gous - 300
HH, for example
Homozygous dominant
______gous - 400
hh, for example
homozygous recessive
_____gous - 500
When two chromosomes on a chromatid are alike, it’s
called…..
homologous

Hodgepodge - 100
Who is the “Father of Genetics”?
Gregor Mendel
Hodgepodge - 200
What is a pea pod?
The outermost casing which holds peas, the delicious
round vegetables, in place.
Hodgepodge - 300
When Gregor Mendel used only purebred pea plants in
his experiments, he was using the principal of:
Selective Breeding
Hodgepodge - 400
Yellow is recessive. For pea pods, which color would
show if you had two recessive alleles?
yellow
Hodgepodge - 500
What’s the probability of having a yellow pea pod when each parent has a homozygous dominant genotype? Green is
dominant
