For a hypothetical gene,how do the terms dominance and recessive relate to gene expression and how genes work?
A)The allele with the dominant phenotype inhibits transcription of the allele for the recessive phenotype.
B)Both alleles get expressed,but the product of the allele with the dominant phenotype masks the phenotype of the recessive allele.
C)A dominant phenotype results in the expression of the most beneficial genes resulting in increased chances of survival of the organism.

The terms dominance and recessive relate to gene expression by determining which allele's phenotype is observable in a heterozygous individual. If an organism has two different alleles for a gene, one dominant and one recessive, the dominant allele will be expressed and the recessive allele will be masked in the phenotype. However, both alleles are still expressed at the molecular level, and the recessive allele can still be transmitted to offspring. This masking effect occurs because the dominant allele produces a protein that is functional or has a stronger effect than the protein produced by the recessive allele.
