Abstract
Genes and chromosomes interplay to produce unique human beings. Each cell contains a pair of sex chromosome. The sperms carry either ‘X’ or ‘Y’ chromosome, thus, they determine the sex of the offspring. Every couple happily accepts their first child, whether a girl or boy. Authors have developed a scientific hypothesis on the basis of which the couple can naturally choose the gender of their second baby at the time of conception. According to theory, ‘Y’ sperms are faster than ‘X’ sperms but they have a shorter life span. The emplacement of ovum occurs after the rise in temperature due to which coitus after ovulation results in a male zygote and vice versa. The authors have also discussed the relation of ovulation and basal body temperature. This hypothesis can result in bringing the population under control and remove many social ills such as female feticide and infanticide from the society.
