पर्याय

• 25%

• 50%

• 75%

• 100%

Answer 1

100%

Explanation:

• Parent genotypes: VV (homozygous dominant) × vv (homozygous recessive); gametes are V and v, respectively.
• All offspring receive V from the first parent and v from the second, so every F1 is Vv (heterozygous). Because V is dominant, all Vv individuals show the violet flower phenotype.
