What is incomplete dominance?

Back

A type of inheritance pattern where the phenotype of the heterozygote is an intermediate blend of the two homozygous phenotypes.

Front

What is codominance?

Back

A type of inheritance pattern where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Front

In a Punnett square, what does a 0% chance of a phenotype indicate?

Back

It indicates that the phenotype will not appear in the offspring based on the genetic combinations of the parents.

Front

If both parents have wavy hair (SC), what is the probability of their child having wavy hair?

Back

50%.

Front

What are the genotypes for straight hair, curly hair, and wavy hair in incomplete dominance?

Back

Straight hair (SS), Curly hair (CC), Wavy hair (SC).

Front

What is the phenotype of a calico cat?

Back

A calico cat exhibits both orange and black fur, demonstrating codominance.

Front

How does incomplete dominance differ from complete dominance?

Back

Incomplete dominance results in a blended phenotype, while complete dominance results in one phenotype being fully expressed over the other.

Front

What is the expected phenotype ratio for offspring from two heterozygous parents (SC) in incomplete dominance?

Back

1 straight (SS): 2 wavy (SC): 1 curly (CC).

Front

What is the significance of a Punnett square in genetics?

Back

A Punnett square is a tool used to predict the genotypes and phenotypes of offspring from parental genetic combinations.

Front

What does it mean if a trait shows codominance?

Back

It means that both alleles contribute equally and visibly to the phenotype of the organism.
