Steroid hormones easily diffuse through the cell membrane. The hormone binds to its receptor in the cytosol, forming a receptor–hormone complex. The receptor–hormone complex then enters the nucleus and binds to the target gene on the DNA.

What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.
