This chemical is DNA.

The characteristics of an individual are controlled by genes through specificity in the synthesis of proteins. In another words, gene expression depends on the type of protein synthesized by that gene.
Traits in organisms are controlled by genes, which are specific segments of DNA that code for different characteristics. Genes can be inherited from parents and influence the physical and behavioral traits of an organism. Environmental factors can also play a role in determining which genes are expressed and how traits are developed.

DNA, or deoxyribonucleic acid, is a molecule that carries genetic information in living organisms. It determines traits and characteristics passed down from parents to offspring. DNA is essential in genetics and heredity as it controls the development and functioning of organisms.
Your testes control male characteristics. Testes are not glands. They are organs.

In the cytoplasm, because that is where the chemical reactions happen.
Heredity in organisms is controlled by genes, which are segments of DNA that encode specific traits. These genes are passed down from parent to offspring through the process of reproduction. The combination of genes an organism inherits determines its characteristics, such as eye color or height.
On my Science homework was the question What controls Inherited Traits? After reading through my text book I discovered that Inherited traits are controlled by genes. So, the answer to the questtion is genes!
