During an experiment, a scientist crosses a pea plant that has purple flowers with a pea plant that has white flowers. The plants that result from this cross in the F1 generation have both purple and white flowers. What can the scientist conclude?
White flowers are dominant over purple flowers.
Neither purple flowers nor white flowers are dominant.
The plants in the P generation were not true-breeding.
All the plants in the F2 generation will have purple flowers.

The plants in the p generation were not true breeding. If they were, all of the flowers in the F1 would be purple or white, depending on which was dominant. You would then see an appearance of the recessive phenotype/genotype in the F2 generation.

The scientist can conclude that the plants in the P generation were not true-breeding.

What is a heterozygous organism?

A heterozygous organism is an individual that carries different alleles for a given gene locus.

In a cross of a dominant phenotypic trait, the presence of both traits in the F1 generation is evidence that parents were heterozygous.

In conclusion, the scientist can conclude that the plants in the P generation were not true-breeding.
