ARTICLE REVIEW
The sex of a kid in the mother's womb is determined by a multitude of variables, as indicated
in this article. One of the reasons is the mother's nutrition. “You are what your mother eats:
evidence for maternal preconception nutrition impacting foetal sex in humans,” according to
the paper. In some species, mothers' facultative adjustment of sex ratios has been linked to
resource availability (Mathews, Johnson and Neil, 2008). Variations in mating systems,
social hierarchies, and litter sizes obstruct the search for consistent patterns in animals. Low
fertility, substantial maternal investment, and a potential difference: these factors should
favour the formation of elective sex variation. The natural mechanisms of sex distribution in
humans, on the other hand, are less well understood. Women in the highest third of
preconception energy intake had boys 56 percent of the time, whereas those in the worst third
bore boys 45 percent of the time. Intakes during pregnancy were not linked to sex, implying
that the foetus has little influence upon the mother's diet..
Another article named as “Maternal Diet and Other Factors Affecting Offspring Sex Ratio:
A Review” pointed this thing. Trivers and Willard showed out that some guys, usually the
bigger and more aggressive in Polygynous species, represented the bulk of reproductive
success in their lives whereas males of the lower rank often did not have any children
(Rosenfeld and Roberts, 2004). In contrast, the great majority of women fall pregnant with
this choice of men regardless of socioeconomic level or physical condition. In such species
fathers often have a small part to play in raising their kids. The sex-allocation theory
proposed by Trivers and Willard predicted that women in the best physical shape will have
children whose gender favours the sex with the most variety, namely males. Trivers and
Willard's sex-allocation hypothesis has provided a reasonable evolutionary explanation for
adaptive differences in sex ratio in ruminant ungulate species, although there are exceptions.
In the findings made by Cramer and Lumey, (2010) “Maternal Preconception Diet and the
Sex Ratio”. This can be explained by the fact that temporary changes in the sex ratio,
including social changes, war situations and environmental changes were thoroughly
explored and linked with girls at birth. The direct proof of each pregnancy and the relation
between mother's preconception nutrition and birth sex demonstrated The writer examined
the theory using fresh information from the famine in Holland between 1944 and 1945, and
