Sadie · Answer 1

The progeny produced is 100% heterozygous individuals.

Explanation:

Remember that in Mendel crosses, there are two alleles for each character, in this case for the color of the flowers.

When the problem refers to pure varieties, it refers to individuals with two equal alleles for the same gene.

If two pure varieties with antagonistic characters intersect, 100% of heterozygous individuals will be obtained in the offspring.

As for its phenotype, it will depend on which allele is dominant over the other.
