In this genetic cross, we have two plants: one heterozygous for orange flowers (let's denote the alleles as O for orange and o for purple, so the genotype is Oo) and one homozygous recessive for purple flowers (which would be oo).
When we cross these two plants, we can set up a simple Punnett square:
- The heterozygous orange-flowered plant (Oo) can produce two types of gametes: O and o.
- The homozygous purple-flowered plant (oo) can only produce one type of gamete: o.
The potential offspring genotypes from this cross would be:
- From Oo x oo, we get:
- Oo (orange-flowered)
- oo (purple-flowered)
Thus, the offspring will have the following ratios:
- 1 Oo (orange)
- 1 oo (purple)
This gives us a ratio of:
- 1 orange: 1 purple
In terms of color ratios, this is equivalent to:
- 1 purple: 1 orange
Since none of the given options exactly state this ratio, check if there's a slight misunderstanding in the available options, or if the this is the expected outcome to derive from the genetic information given. If strictly choosing from the provided options, you would pick the one closest but it seems there's no correct match.
Based on the results, the best option matching your setup is actually not available among the choices listed.
