Codominance Punnett Squares

Front

What is codominance in genetics?

Back

Codominance is a genetic scenario where both alleles in a heterozygous individual contribute equally and visibly to the organism's phenotype.

Front

What do we call the different forms of a gene?

Back

Alleles.

Front

How many alleles does an individual have for each trait?

Back

2.

Front

What is an example of codominance in animals?

Back

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

Front

What is the result of a Punnett square for codominance?

Back

The Punnett square will show offspring with a mix of both parental traits.

Front

What is the phenotype of a heterozygous chicken with black and white feather alleles?

Back

Speckled black and white feathers.

Front

What type of inheritance pattern shows both traits in possible offspring?

Back

Co-dominance.

Front

What is the difference between codominance and incomplete dominance?

Back

In codominance, both traits are fully expressed, while in incomplete dominance, the traits blend to form a new phenotype.

Front

What is a Punnett square used for?

Back

A Punnett square is used to predict the genotypes and phenotypes of offspring from parental crosses.

Front

What does it mean if an allele is dominant?

Back

A dominant allele is one that expresses its trait even when only one copy is present.
