Are allergies genitic

Answer 1

There is currently believed to be both a genetic component and an environmental component to Allergies.

Children who have a close relative with an allergic condition -- Asthma, hay fever, environmental allergies, or food allergies -- are more likely to develop an allergy as they grow older. And people who have one of those conditions are at greater risk of developing another.

Because people living in urban areas, wealthier families, and first-world countries are at somewhat greater risk of developing allergies relative to people in rural areas, poorer families, and third-world countries, many scientists have speculated that there may be environmental factors at work that can raise one's risk of developing allergies later in life. But it's not yet been determined what, precisely, those factors are.
