“…As for the genetic components, Dolton and Xiao (2015), Locke et al (2015), Herrera et al (2011), Savona-Ventura and Savona-Ventura (2015), Biroli (2015), Cawley et al (2017) and Brunello et al (2019) consider that part of obesity is transmitted through this route, so the presence of parents or family members with obesity makes children more likely to suffer from it. In this sense, Atella et al (2008), d'Hombres (2005, 2007), Norton and Han (2008), Kortt and Leigh (2010), Lindeboom et al (2009), Cawley et al (2005), Cawley (2000Cawley ( , 2004, Shimokawa (2008), von Hinke Kessler Scholder et al 2010 Conley (2009) have shown that the current knowledge of genetics and its uses in the social sciences is debatable, as there is not enough knowledge to know if the genes related to obesity are not related to other components which are in turn related to the employment and productivity of people.…”
