A geneticist discovered a new species of flower with very bright red petals (R) which are dominant to white petals (r), and round leaves (L) which are dominant to oblong leaves (l). She wanted to observe what the offspring would look like when she crossed the following two individuals: RRLl x rrll. Which of the following best describes the parent’s phenotypes?

A. RRLl has red petals and round leaves; rrll has white petals and oblong leaves
B. RRLl has red petals and oblong leaves; rrll has white petals and round leaves
C. RRLl has white petals and round leaves; rrll has white petals and oblong leaves
D. RRLl has white petals and oblong leaves; rrll has red petals and round leaves
E. RRLl has red petals and oblong leaves; rrll has red petals and round leaves

According to the given information, the allele for red petals (R) is dominant to the one for white petals (r). And the allele for round leaves (L) is dominant to the allele for oblong leaves (l).

The parental genotype RRLl would have both the dominant traits as it is homozygous dominant for petal color and heterozygous dominant for the shape of leaves. This parent would have red petals and round leaves.

The other parent with genotype rrll is homozygous recessive for both the traits and therefore, would express both the recessive traits. This parent will have white petals and oblong leaves.

The parent's phenotype, according to the illustration, would be red petals with round leaves and white petals with oblong leaves respectively.

Phenotypes

This refers to the physical appearance of organisms.

R conditions red petals and is dominant over r which conditions white petals.

L conditions round leaves and is dominant over l which conditions oblong leaves.

Thus, RRLl parent will have red petals with round leaves while rrll parent will have white petals with oblong leaves.
