Question

Roses may grow single flowers or double flowers. Double flowers have morepetals than single flowers and are highly prized by gardeners. However, theseextra petals may block or replace parts of the flower needed for reproduction,This makes double flowered plants difficult to breed.In a group of rose plants, some individuals have double flowers and others have singleflowers. In this group, the gene for the flower form trait has two alleles. The allele for singleflowers (1) is recessive to the allele for double flowers (F).A certain rose plant from this group has the homozygous genotype ff for the flower formgene. NBased on this information, what is this plant's phenotype for the flower form trait?double flowerssingle flowers

Answer 1

As the rose plant has a ff homozygous genotype, it can express the recesive phenotype which is single flowers.
