Body fat can be divided into white fat and brown fat.
White fat cells (adipocytes) have a <u>single lipid droplet</u> and this fat is a result of an excess of calories. White fat, when storage around abdominal area, increases cardiovascular risk. Therefore, an <em>obese person has a great proportion of this type of fat.
</em>
On the other hand, brown fat has <u>many lipid droplets</u> and <u>mitochondria full of iron</u>, which give its brown color. Brown fat is useful to generate heat, it does so by burning calories. This type of fat can usually be found in adults in the back of the neck and above the collarbone and its amount <em>decreases with age. </em>

Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.
