Question

genetic factors in inheritance quick check
consider that a plant with genotype srs has red flowers, and a plant with genotype www has white flowers. this plant species expresses incomplete dominance for flower color when the plant is heterozygous.
the offspring of a cross between an srs plant and a www plant would be
(?) pink?
○ all white
○ pink and white
○ all pink
○ red and pink

Explanation:

Step1: Identify parent genotypes

Parents: $RR$ (red) and $WW$ (white)

Step2: Determine gametes each parent produces

$RR$ produces only $R$ gametes; $WW$ produces only $W$ gametes.

Step3: Predict offspring genotypes

All offspring get one $R$ and one $W$, so genotype $RW$.

Step4: Apply incomplete dominance rule

Heterozygous $RW$ = pink flowers (given incomplete dominance).

Answer:

all pink
