Question
Codominance is when the phenotype (physical characteristics, what it looks like) of both alleles are expressed in offspring. For example, a white cow (WW) and a red cow (ww) produce a roan cow (Ww, red and white spotted). Which of the following is an example of codominance? (MARK ALL THAT APPLY)
a spotted cow
multi-colored flower petals
blood types
a gray cat
a spotted cow
multi-colored flower petals
blood types
a gray cat

Codominance is indeed characterized by the expression of both alleles in the phenotype of the offspring. In the options you provided:
1. **A spotted cow** - This is an example of codominance because both white and red color traits are expressed in spotted patterns.
2. **Multi-colored flower petals** - If the multi-colored petals result from two different colored alleles being expressed simultaneously, this might also represent codominance.
3. **Blood types** - This is a classic example of codominance. For example, individuals with the genotype I^A I^B have type AB blood, expressing both A and B antigens.
4. **A gray cat** - Gray color in cats is typically the result of a dilution trait rather than codominance, so this does not represent codominance.
Based on this understanding, the correct answers that exemplify codominance are:
- **a spotted cow**
- **multi-colored flower petals** (if specifically describing the expression of two different colors)
- **blood types**
So, the answers are: a spotted cow, multi-colored flower petals, and blood types.
