Men who drink heavily are more likely to have teetotal sons, new study reveals

• A father's drinking does not influence his daughters' alcohol consumption Men's drinking could affect their son's genes before they are conceived
• 
  
• Their sons tend to drink less and to be more sensitive to the effects of drink
  
  
  
  
• Men who drink heavily are more likely to have sons who shun alcohol in later life, new research suggests.

However, the study also showed the fathers’ drinking has no effect on their daughters’ alcohol intake. 

Lab experiments suggest the drinking behaviour of men influences their male offspring’s genes before they are even conceived.

But surprisingly, there was no effect on their female offspring.
