Let's say a 20 year old man named Peter, has below normal health due to his smoking habit and a lifestyle of poor nutritional diet. He has a child with his wife and a daughter is born.
During the next 5 years, Peter changes his lifestyle drastically. He quits smoking and improves his diet. Further, he also embarks on a regimented exercise program and builds an impressive physique. He becomes an athlete. At age 25, he has another daughter.
Considering all other things constant (wife has no changes in her lifestyle and neither has the first born), will the second daughter possess superior genes?
Thank you for your insight.
