Genetics Practice Questions
1. Patrick loves growing flowers for his pal Squidward! His favorite flowers, Puffkins,
are found in red, yellow, and orange. Use the information provided and your
knowledge of incomplete dominance to complete each section below.
a. Write the correct genotype for each color if R represents a red gene and Y
represents a yellow gene. Red-? Yellow-? Orange-?
b. What would happen if Patrick crossed 2 orange puffkins? Complete a
Punnett square to determine the chances of each flower color.
2. In a certain breed of breed of velociraptors, when a blue raptor (BB) crossed with
a green raptor (GG) all of the offspring were punon- a spotted green and blue
color. What is the expected phenotype and genotype for the offspring if a punon
raptor mates with a blue raptor?
3. A leopard named Leo had purple spots, which was dominant to red spotted
leopards. Leo had short legs which was recessive to long legged leopards. If
Leo, a homozygous dominant purple-spotted leopard has children with a redspotted leopard with long legs, but their mom had short legs, what is the
genotype, and phenotype ratios for the children?
4. Janeckrandy Syndrome is recessive sex-linked condition where you are born
with color changing hair that changes depending on your mood. The mom suffers
from the condition and she marries a normal hair colored male. What is the
genotypes and the phenotypes of the parents and their children?
5. One day while cleaning the guillotines, Mr. Mort passes the time crosses the
traits of random blood samples, blood type being a multiple alleles trait, with A
and B being dominant to O, yet neither is dominant over the other. He crosses a
heterozygous type A blood sample with a homozygous type B blood sample.
What would the phenotypic and genotypic ratios of their theoretical offspring.
6. Lily is a pig. She is homozygous dominant for the trait of having a curly tail. Her
mate Max has the trait for having a straight tail. Predict the genotypic and
phenotypic ratios of their children.
7. A person who can roll his/her tongue has a dominant trait. A male with ability of rolled
tongue married a female who can’t roll her tongue. And one of their children cannot roll
his tongue, define his parent’s genotype?
8. Teal Peacocks are dominant to beige Peacocks. Short feathers are recessive to
long feathers. If a heterozygous teal Peacock with short feathers mates with a
beige homozygous long feathers. What would the baby Peacocks geno and
phenotypes be?
9. Bonnie is heterozygous blood type A. Chad her husband, is blood type AB. What
are the predicted phenotypic and genotypic ratios of their offspring? What is the
expected outcome of a child being a universal receiver? Universal donor?
10. A black swallow (BB) crossover a white swallow (WW) will create a gray swallow (BW)
a. A homozygous dominant black swallow (BB) mated with a heterozygous gray
swallow (WW) what is the chance they will have gray (BW) colored offspring?
b. What is the chance to have black colored offspring?
11. The looseness of knee caps is a sex linked dominant trait. A man with tight knee caps
marries a woman with a heterozygous trait for loose kneecaps. What will the outcomes
of their offspring be?
12. Dogs can either be blue or green. These color traits are codominant. If a blue
and green spotted dog and a green dog mate, than what percent of their
offspring will be blue?
