A gene is a DNA segment and a functional unit of inheritance. A dominant gene generally expresses and shows itself over a recessive gene. Thus, option c is correct.
What are dominant and recessive genes?
Dominant genes are the variant of genes that expresses their allele and character in both purebred and heterozygous conditions. While the recessive genes are the other variant of the gene that expresses its traits only in a purebred condition.
The dominant genes or alleles are superior and prevail over the recessive gene by masking and overriding them in heterozygous conditions. A dominant gene is depicted by capital letters and recessive by small letters.
Therefore, the dominant gene overrides the recessive gene.
