Due to the difference in sex ratio what would be the impact on society explain

Answer»

ating and reproductive behaviour can vary depending on various mechanisms, including the LOCAL sex ratio. Previous RESEARCH shows that as sex ratios become female-biased, women from economically deprived areas are less likely to delay reproductive opportunities to wait for a high-investing mate but instead begin their reproductive CAREERS sooner. Here, we show that the local sex ratio also has an IMPACT on female fertility schedules. At young ages, a female-biased ratio is associated with higher birth rates in the poorest areas, whereas the opposite is true for the richest areas. At OLDER ages, a female-biased ratio is associated with higher birth rates in the richest, but not the poorest areas. These patterns suggest that female–female competition encourages poorer women to adopt a fast life-history strategy and give birth early, and richer women to adopt a slow life-history strategy and delay reproduction.
