Codominance vs incomplete dominance

Front

What type of inheritance occurs when two alleles blend together in the phenotype?

Back

Incomplete Dominance

Front

In a Punnett square showing incomplete dominance, what percentage of the offspring will be white if the parental genotypes are black and gray?

Back

0% (if black and gray are the only alleles present, white cannot be produced).

Front

What is the term for a genetic scenario where both alleles in a heterozygote are fully expressed?

Back

Codominance

Front

What does a Punnett square representing incomplete dominance indicate about the offspring's phenotypes?

Back

The offspring will show a blend of the parental traits.

Front

How do incomplete dominance and codominance differ from a typical Mendelian cross?

Back

In incomplete dominance and codominance, the heterozygous genotype results in a unique phenotype, unlike in Mendelian inheritance where one allele is completely dominant.

Front

What is an example of codominance in animals?

Back

The AB blood type in humans, where both A and B alleles are expressed.

Front

What is the expected phenotype ratio in a monohybrid cross exhibiting incomplete dominance?

Back

1:2:1 (one homozygous dominant, two heterozygous, one homozygous recessive).

Front

In codominance, how are the alleles expressed in the phenotype?

Back

Both alleles are fully expressed, resulting in a phenotype that shows both traits distinctly.

Front

What is the main characteristic of incomplete dominance?

Back

The phenotype of the heterozygote is an intermediate blend of the phenotypes of the two homozygotes.

Front

Can you provide an example of incomplete dominance in plants?

Back

The flower color in snapdragons, where red and white flowers produce pink offspring.
