Since after crossing a red and a white flower produced pink flowers, the red color trait shows an incomplete dominance and has a genotype of Rr. Using the Punnett to determine the cross between pink and white flowers: | R | r | r | Rr | rr | r | Rr | rr |
The results indicate that the cross between pink and white flowers will produce a ratio of 1:1
I think this layer formed by the strong currents or by waves slowly moving the shells to the shore along with other shells creating a layer of shells. If I’m wrong then I’m sorry:(
