1. Incomplete or Co-Dominant?!?!

2. Normally traits have one dominant allele and one recessive allele…. What happens when an allele for a trait isn’t completely dominant over the other allele?

3. If red isn’t dominant over white and white isn’t dominant over red – what will the offspring look like??

4. This is called Incomplete Dominance

5. Key: RR = Red WW= White RW= Pink RW R R W W If a red flower crosses with a white flower show the possible offspring below:

6. Normally traits have one dominant and one recessive allele…. What happens when both alleles of the trait contribute to the phenotype of the organism?

7. If red is dominant but white is also dominant– what will the offspring look like??

8. This is called Codominant

9. +

10. Key: RR = Red WW= White RW= red with white spots RW R R W W If a red flower crosses with a white flower show the possible offspring below:
