The trait for purple flowers in this scenario is dominant, following Mendel's principles of genetics.
In this case, the trait for purple flowers is dominant. When a purebred purple flowering plant is crossed with a purebred white flowering plant, and the offspring have purple flowers, it indicates that the purple flower trait is dominant over the white flower trait. This inheritance pattern follows Mendel's principles of dominant and recessive traits in genetics.
Mendel, through his experiments on pea plants, established that traits can be dominant or recessive. In this scenario, the purple flower trait being expressed in the offspring suggests it is the dominant trait. The Punnett square and probability calculations reinforce the dominance of the purple flower trait.
Understanding dominant and recessive traits is fundamental in genetics, as it helps predict the outcomes of crosses between different individuals with known genetic information.
