The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.

Answer:
The correct answer is- Immune system
Explanation:
There are physical, chemical and immunological barriers present in our body which helps us to protect from the foreign antigen. They all assist each other and helps in pathogen removal from our body.
The physical barrier includes skin, gastrointestinal tract, respiratory tract, etc which do not allow the microbe to enter the body. Chemical barriers include tear, saliva, acid in the stomach which kills microbes on the body surface.
Immune cells like macrophages, B cells kills microbes when it gets in the body. Lymphatic system also contain immune cells and helps in microbe removal.
So the immune system is assisted by physical barrier, chemical barrier, and lymphatic system.
This would be incomplete dominance
