Total questions: 15
Worksheet time: 15mins
This is an example of ___________?
Incomplete dominance
Co-Dominance
Complete dominance
What do you call the non-Mendelian inheritance pattern that states that neither trait is dominant and the traits appear to blend together?
Codominance
Incomplete dominance
Polygenic traits
A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?
Incomplete Dominance
Codominance
Independent assortment
Recessive inheritance
This flower would be an example of which inheritance pattern?
polygenic traits
incomplete dominance
multiple alleles
codominance
This type of inheritance pattern shows BOTH traits in possible offspring
complete dominance
incomplete dominance
co-dominance
dominant pattern
A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:
all black
all white
all gray
speckled black and white
In a heterozygous offspring, there is a blending of the traits.
Codominance
Incomplete Dominance
Complete Dominance
This rooster's mother was all black and its father had all white feathers. What type of inheritance explains its appearance?
simple dominant/recessive
epistasis
incomplete dominance
codominance
In Mendel's experiments, which type of dominance is characterized by the blending of traits in the heterozygous state?
Codominance
Incomplete Dominance
Complete Dominance
Overdominance
Which of the following is an example of codominance in plants?
A red and white flower producing pink offspring
A red flower and a white flower producing red and white striped offspring
A red flower producing only red offspring
A white flower producing only white offspring
In a genetic cross involving incomplete dominance, what would be the expected phenotype ratio in the F2 generation?
1:2:1
3:1
9:3:3:1
1:1
Which of the following best describes the phenotype of a heterozygous individual in a case of incomplete dominance?
A blend of both parental traits
Only the dominant trait is expressed
Both parental traits are fully expressed
Neither trait is expressed
In a codominant inheritance pattern, what would be the phenotype of an organism with genotype R1R2 , where R1 codes for red color and R2 codes for white color?
All red
All white
Red and white patches
Pink
Which experiment would best demonstrate incomplete dominance?
Crossing red and white snapdragons to produce pink offspring
Crossing red and white roses to produce red and white striped offspring
Crossing two red flowers to produce only red offspring
Crossing two white flowers to produce only white offspring
In a case of codominance, if a black chicken and a white chicken are crossed, what is the expected phenotype of the offspring?
All black
All white
All gray
Speckled black and white
