a plant with white flowers was crossed with a plant with red flowers. all of the offspring had pink flowers. which of these terms describes the red flower color trait?
a dominant
b recessive
c sex-linked
d incomplete dominance

Explanation:

When a white-flowered plant is crossed with a red-flowered plant and all offspring have pink flowers, this shows a pattern where neither the red nor white trait is fully dominant. Instead, the heterozygous offspring show an intermediate phenotype, which is the definition of incomplete dominance. The red flower trait itself, in this context, does not act as dominant (since it doesn't mask white) or recessive, and there is no indication of sex-linkage.

Answer:

D. incomplete dominance
