It is not accurate to say that men are fat and easy to have daughters. Because having boys and girls is determined by genes, the probability of having boys and girls is 50% each. If your husband provides the X gene, it is a girl, and if it is the Y gene, it is a boy. This has nothing to do with whether your husband is fat or not, so there is no saying that being fat is easy to have girls. Genes are all nucleotide sequences needed to produce polypeptide chains or functional RNA. Genes support the basic structure and expression of life. It stores all the information about race, blood type, gestation, growth and apoptosis of life.
