Answer:
25% heterozygous tall
Explanation:
If we take the F1 generation as parents and let them self-fertilise, we have 4 crosses.
The first one for homozygous tall, then we have 100% AA.
The second and third one for heterozygous tall and we have 25% AA, 50%Aa and 25%aa for each of them.
The last one would be for dwarf, and we'll have 100%aa.
Adding all of them, we'll have
AA = 100 + 25 + 25 = 150%
Aa = 50+50 = 100%
aa = 100 + 25 + 25 = 150%
as we had 4 crosses, so dividing the total percentages by 4, we'll have,
AA = 37.5%
Aa = 25%
aa = 37.5%
:. The percentage of heterozygous tall would be 25%.

Stress initiates biological changes involving the autonomic and endocrine systems, as well as the system that helps the body ward off illnesses, the immune system.
<h3>What is the immune system?</h3>
The immune system is a body system used by the body to fight against infections and diseases caused by bacteria and viral entities (they are not organisms).
The immune system is composed of physical barriers such as the skin mucous membranes, and endothelia that fight against pathogenic infections.
In conclusion, stress initiates biological changes involving the autonomic and endocrine systems, as well as the system that helps the body ward off illnesses, the immune system.
