Answer:Human height
Explanation:
Inheritance patterns are often more complex than predicted by simple mendalian genetics. When Mendel studied some phenotypic characters, like the human skin color and height, they were found to be an addictive effect of two or more genes on a single phenotypic character. These are called quantitative characters, which usually indicates polygenic inheritance.
The human height is an example of quantitative character, it is controlled by at least 3 genes having 6 alleles. 3 genes with 6 alleles from both parent can give rise to wide range of phenotypic character (heights).
The National Institutes of Health found it effective in reducing pain and other symptoms, but it is not clear how it works.
Answer:
The answer is D because it is the only example that takes place over a long period of time.
Explanation:
Rhinitis is an allergic condition characterized by inflammation in the mucus membrane lining of the nose. The anti-histamine nasal sprays controls the symptoms of allergy but it has rebound effect which means that though the sprays works well in controlling the disease, it still causes inflammation and damage to the mucus membrane lining of the nose that may lead to nausea and bleeding of nose.
