In snapdragons, flower color is determined by a single gene with two alleles. red flowers (R) are incompletely dominant over white flowers (r). if a plant with red flower (RR) is crossed with a plant with white flowers (rr), what will be the phenotype of the offspring?

Question

all red
all white
all pink
50% red, 50% white

Answer 1

In snapdragons, where red flowers (R) are incompletely dominant over white flowers (r), a cross between a plant with red flowers (RR) and a plant with white flowers (rr) will produce all offspring that have the genotype Rr.

Since the R allele is incompletely dominant, the heterozygous phenotype (Rr) will show an intermediate phenotype, which in this case will be pink flowers.

Therefore, the phenotype of the offspring will be all pink.

Answer 2

r u sure

Answer 3

I apologize for any confusion in my previous explanation—let's clarify that.

In the case of snapdragons, where red flowers (R) are incompletely dominant over white flowers (r), the following occurs during the cross:

• A plant with the genotype RR (red flowers) crossed with a plant with the genotype rr (white flowers) will produce offspring that are all Rr.
• The genotype Rr will produce a flower color that is intermediate between red and white, which is typically pink.

So, the correct answer to your question is indeed all pink flowers in the offspring. Thank you for your patience!
