Which trait will an organism that receives one dominant gene and one recessive gene most
likely have?

The dominant gene - such as brown hair or brown hair

Explanation:

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked. A person with two dominant or two recessive alleles for a trait is "homozygous." A person with one dominant and one recessive allele for a trait is "heterozygous." Because a boy inherits only one X-chromosome, if there is a recessive gene on that X-chromosome, the gene is expressed.

the answer is 75.0%.
