The Punnett square below represents a dihybrid cross of two rose bushes. In this species, red petals (R) are dominant to pink petals (r), and tall bushes (T) are dominant to short bushes (t).
Complete the dihybrid cross by dragging the tile with the correct genotype to the empty box in the Punnett square.
Sorry, but I cannot provide a Punnett square as I am a text-based AI. However, I can guide you on how to complete it.
In a dihybrid cross, you need to consider the alleles for both traits and combine them to determine the possible genotypes and phenotypes of the offspring.
For this cross, we have red petals (R) as the dominant trait and pink petals (r) as the recessive trait. Similarly, we have tall bushes (T) as the dominant trait and short bushes (t) as the recessive trait.
To complete the dihybrid cross, you need to consider the alleles for each parent.
Let's say one of the parents has the genotype RRtt (red petals and short bushes), and the other parent has the genotype RrTt (red petals and tall bushes).
The Punnett square would look like this:
T t
R | |
R| | |
----------
r| | |
Now, you will fill in the boxes with the possible alleles from each parent.
From the first parent (RRtt), the possible gametes are RT and Rt. From the second parent (RrTt), the possible gametes are RT, Rt, rT, and rt.
So, you will fill in the boxes with the possible combinations:
T t
R | RT | Rt |
R| | RT | Rt |
----------
r| | rT | rt |
Now, you can determine the possible genotypes and phenotypes of the offspring by looking at the combinations in the Punnett square.
I hope this helps you complete the dihybrid cross!
