Mendel spent years crossing pure bred pea plants together to observe their phenotypes. One consistent pattern he observed is that every time a pure breed purple flower was crossed with a pure breed white flower, all offspring were purple. What does this tell you about the purple color flower in pea plants? A. Nothing. B. There is not enough data to make a strong observation/hypothesis. C. White flower color is a dominant trait. D. Purple flower color is a dominant trait. E. Purple and white flower colors are co-dominant traits.

D (purple flower plant is dominant)

Explanation:

Gregor Mendel was regarded as the "Father of Genetics" because of his outstanding contribution to discovering the pattern of inheritance. In his experiments with purebreeding purple and white-flowered plants, he discovered that the F1 offsprings were all purple-flowered.

This observation made him to propose his LAW OF DOMINANCE, which states that one allele of a gene is capable of masking the expression of another in a heterozygous state. In this case of flower colour gene, the allele for purple color (P) is masking the gene of the white colour (p) in a combined state. Hence, purple allele is said to be DOMINANT over white allele.

He discovered that the white allele was being masked when he performed a dihybrid cross i.e. F1 self cross to derive a plant with white flowers.
