"Dominant Gene:

1. Dominant genes are those which express the dominant trait in a species.

2. Dominant genes can either be homozygous or heterozygous, that is, it can possess either both the ""dominant alleles"" or ""one dominant"" and ""one recessive allele"".

3. Example: Smooth seed coat of peas.
