A student claims that the inheritance pattern for kernel coating is

incomplete dominance.

Which of the following pieces of evidence best supports the student's cla

(1 point)

O Corn and teosinte share the scientific name Zea mays.

Early farmers produced corn by selectively breeding teosinte.

A single gene with two alleles codes for the presence or absence of kernel coating in

Zea mays.

The cross between domestic corn and teosinte produced offspring with partially formed

Verified Answer :

The best evidence supporting the student's claim of incomplete dominance would be:

"The cross between domestic corn and teosinte produced offspring with partially formed kernel coating."

This evidence suggests that when one parent with a dominant phenotype (kernel coating) is crossed with another parent with a recessive phenotype (no kernel coating), the offspring exhibit an intermediate phenotype (partially formed kernel coating), which is characteristic of incomplete dominance.
