In many different places to find them. Like pancreas, ovaries, testes, thyroid, parathyroid, hypothalamus, and neuro-endocrine organs.<span>

Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.

A single germ line mutation can have a range of effects:
<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>

Answer:
The term that describes that individuals understand themselves as being either male or female is called <u><em>gender identity </em></u>while the understanding that maleness and femaleness are biological and cannot change is <u><em>gender constancy</em></u>.
Explanation:
Gender identity can be described as a personal perception of considering oneself as a male or female ( or both or none). It is a realization that which characteristics you possess and according to these characteristics or traits, you will fit into which sex.
Gender constancy can be described as the understanding that the biological sexes are fixed and permanent. It is a realization that changes in the gender cannot occur even if an individual changes his appearance or traits.
