english: As geneticists would like you to think, perhaps the mother had the "bad mother" gene that caused her pups to be stressful, and then it was passed from generation to generation; it's all determined by genetics.
non_english: Genetikçilerin düşünmenizi istediği gibi, belki de annede yavrularda strese sebep olan "kötü anne" geni vardı ve bu nesilden nesile aktarıldı; bütün bunlar genlerle belirlenmişti.
