I believe it’s the first option
This process is is called controlled breeding. This allows the farmer to breed the offspring in such a way that only the genes that he wants present are produced in the offspring.
It is the Epithelium and blood-forming tissue. Endothelial cells are epithelial cells that shape a thin layer of straightforward squamous epithelium known as the endothelium. Vein endothelium is nonstop with the inward tissue coating of organs, for example, the mind, lungs, skin, and heart. Endothelial cells are gotten from endothelial undifferentiated organisms situated in bone marrow.
Adaptations are
the result of evolution in different living organisms. This process occurs amazingly
through gene mutation but it takes a very long period in time. Adaptation processes
occur to help species survive and thrive in the ecological balance of life.
Structural adaptations are physical features of an organism that adapted through
time. An example of this are the bills of a bird and the fur of bears that they
generally need for their survival; birds for hunting, and bears to protect them
from low climate areas.

Functional or
Behavioral adaptations refer to particular things that an organism or organisms
do to survive. In the example above, behavioral adaptations that birds do is
through certain bird calls and migration, while bears hunt during warmer
seasons and hibernate during winter season. </span>
