Answer:
Epistasis
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants
In Genetics, a gene pair has the ability to influence other gene pairs based on their combined activities which produces some effect on phenotype; this is called epistasis.
The two types are Alcoholic fermentation and lactic acid fermentation.
They were plants that preferred a warm temperature and couldn't survive in a cold one.
They discovered these plant fossils in Svalbard, Norway, which was once home to a forest. They were thought to have originated in a tropical jungle that was close to the equator. However, these fossils were discovered in the north, where the environment prevented their growth. This demonstrated that these trees were transported by continental drift to the northern, colder region that is now Norway.
