Question

in a group of rose plants, some individuals have light yellow flowers and others have dark yellow flowers. in this group, the gene for the flower color trait has two alleles. the allele for light yellow flowers (f) is dominant over the allele for dark yellow flowers (f).
a certain rose plant from this group has the heterozygous genotype ff for the flower color gene.
based on this information, what is this plants phenotype for the flower color trait?
dark yellow flowers
light yellow flowers

Explanation:

Dominant alleles (F) express their phenotype even when paired with a recessive allele (f). The plant has a heterozygous genotype Ff, so the dominant trait (light yellow flowers) will be observed.

Answer:

light yellow flowers
