VP #4: Incomplete Dominance, Codominance

What is the term used when a dominant allele does not fully express over a recessive allele, resulting in a blend of traits?

• Polygenic inheritance
• Codominance
• Epistasis
• Incomplete dominance

What color are the offspring of a red snapdragon and a white snapdragon?

• Red and white (if the red parent is heterozygous) or all red (if the red parent is homozygous).
• All white
• All pink
• Red, pink, and white

In codominance, what is the phenotype of offspring from a black chicken and a white chicken?

• Black and white speckled chickens
• Gray chickens
• Solid white chickens
• Solid black chickens

How are different letters used in genetic representation?

• Uppercase letters for recessive alleles and lowercase letters for dominant alleles.
• All letters represent the same type of allele regardless of case.
• Only numbers are used to represent genetic traits.
• Uppercase letters for dominant alleles and lowercase letters for recessive alleles.

What does a Punnett square illustrate?

• A Punnett square shows the physical appearance of organisms.
• A Punnett square predicts the lifespan of offspring.
• A Punnett square determines the environmental factors affecting traits.
• A Punnett square illustrates the genetic combinations and probabilities of offspring traits from parental alleles.

Which of the following traits is an example of polygenic inheritance?

• Chicken Color

• Llama Wool Color

• Height
• Snapdragon color

What environmental factor can influence human height?

• Climate change
• Nutrition
• Humidity

• Genetics

What happens to a llama's wool color if it inherits the cc genotype for the epistatic gene?

• The llama's wool color will be black or dark-colored.
• The llama's wool color will be spotted or patterned.
• 
  It becomes speckled

• 
  No pigment is expressed

Why is it important not to assume non-Mendelian inheritance in problem-solving?

• Because Mendelian inheritance is more common

• Assuming Mendelian inheritance simplifies problem-solving.
• Non-Mendelian inheritance is irrelevant to genetic data interpretation.
• It is important not to assume non-Mendelian inheritance because it can lead to incorrect conclusions and misinterpretation of genetic data.
