There are so many examples for that in different areas, like biology experiment carried out in our lab recently.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. In addition, suppose that a dominant allele (L) codes for long eyelashes and a recessive allele (l) codes for short eyelashes. If two individuals heterozygous for both traits (tail color and eyelash length) mate, the probability of the phenotypic combinations of the offspring will be in the ratio, D. 9:3:3:1 ratio (9 polka-dot tails and long eyelashes, 3 polka-dot tails and short eyelashes, 3 solid tails and long eyelashes, 1 solid tail and short eyelash).
The solution is found by solving a Punnett square shown in the image.
Answer:
Gravitational energy
Explanation:
An object's height above the ground (Earth) gives it gravitational energy.
