Angelman syndrome is primarily caused by genetic factors, specifically mutations or deletions in the UBE3A gene on chromosome 15. While environmental factors do not cause the syndrome, they may influence the severity of symptoms or the quality of life for individuals with the condition. For instance, factors such as nutrition, physical activity, and social interactions can play a role in managing symptoms and improving overall well-being. However, the core genetic basis remains unchanged by environmental influences.

Genes whose effect does not normally occur unless certain environmental factors are present are Conditional mutant. The mutant that has a wild type phenotype under certain environmental conditions and a mutant phenotype under other conditions.
The factors that effect human growth and development include nutrition and environmental factors. If a person does not have adequate nutrition their body can not grow properly.
Light intensity, carbon dioxide concentration, and temperature are the main environmental factors that directly influence photosynthesis. Adequate levels of all three factors are necessary for optimal photosynthetic activity in plants.

The main issue of deforestation is the effect it has on the environment, including animal habitat, the CO2/oxygen balance, environmental factors such as erosion, etc.
fetal alcohol effect is not as severe
The age of an individual has the greatest effect on reproductive potential. Fertility decreases with age in both males and females due to factors like declining egg/sperm quality and quantity. Other factors such as overall health, lifestyle choices, and environmental factors can also impact reproductive potential.
