The characteristic that results from a monohybrid cross is the trait.

The answer is dominant.

A monohybrid cross involves organisms that are heterozygous for only one character. In autosomal dominant traits, the phenotype is present if both copies of the dominant allele (A) are present (homozygous individuals AA) or only one copy of the dominant allele is present (heterozygous individuals Aa). Thus, the characteristic that results from a monohybrid cross is the dominant trait.
