dominant trait would be expressed, but they'd be carriers for the
recessive trait.

Answer:
Major difference between active transport and facilitated difusion is:
Active transport moves substances against the concentration gradient.
Facilitated diffusion moves molecules through the plasma membrane.
Explanation:
- Active transport involves the transport of molecules against the concentration gradient.
- Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
- Facilitated diffusion do not require energy but need some other molecule or carrier protein to transport the molecules across the membranes.
- In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
