When we talk about the inheritance of flower color in Snapdragons, we’re dealing with a case of incomplete dominance. In this scenario, red flowers (RR) and white flowers (WW) produce pink flowers (RW) when crossed. If we cross two hybrid pink Snapdragons (RW x RW), we can predict the potential outcomes using a Punnett square.
The possible combinations from this cross are:
- RR (red flowers)
- RW (pink flowers)
- RW (pink flowers)
- WW (white flowers)
This gives us a ratio of:
- 1 RR (red)
- 2 RW (pink)
- 1 WW (white)
From this, we can see that there are 2 pink flowered plants out of 4 total possible outcomes. Therefore, the probability of getting pink flowers in the offspring is:
2 out of 4, or 50% chance.
