Question

A red flower and a white flower can be expressed on a plant depending on genetics which outcome would indicate codominance Ask the inheritance pattern for flower color in this species
A. All offspring or red
B. Is all offspring or white
C. All offspring of a red x white cross would be pink
D. All offspring of a red x white cross would be spotted with red and white both being expressed

Answer 1

In genetics, codominance refers to a situation where both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that clearly displays both traits simultaneously.

Given the options you've provided:

- **A. All offspring are red** - This indicates complete dominance, where the red allele completely masks the white allele.
- **B. All offspring are white** - This is also an example of complete dominance but in the opposite direction.
- **C. All offspring of a red x white cross would be pink** - This indicates incomplete dominance, where the blending of traits results in a new phenotype (pink).
- **D. All offspring of a red x white cross would be spotted with red and white both being expressed** - This indicates codominance, where both red and white traits are expressed distinctly in the offspring.

Therefore, the correct answer that indicates codominance is:

**D. All offspring of a red x white cross would be spotted with red and white both being expressed.**
