The cross between a homozygous round seed-producing plant and a homozygous wrinkled seed-producing plant is a cross between RR and rr. According to the given information, round (R) is dominant over wrinkled (r).
When two parents with different genotypes are crossed, the Punnett square can be used to determine the possible genotypes and phenotypes of the offspring.
The Punnett square for this cross would look like:
R R
---------------
r | Rr | Rr |
---------------
r | Rr | Rr |
---------------
From the Punnett square, we can see that all of the offspring will have the genotype Rr, which corresponds to round seeds. Therefore, the percent of the offspring expected to have round seeds is 100%.
Answer: E. 100%
In pea plants, round is dominant over wrinkled. A homozygous round seed−producing plant is crossed with a homozygous wrinkled seed−producing plant.
