¿Por Qué Tenemos Más Niños Que Niñas?

The video explores the unequal odds of having male and female children, revealing that more boys are born than girls globally. This is due to a biological bias where male zygotes are more common, but male fetuses face higher mortality rates. Environmental factors, such as famine, can influence the gender ratio at birth. In mammals, resource availability affects the number of male births, as males are a higher reproductive risk but offer greater potential for gene propagation when conditions are favorable.
