Detailed explanation-1: -Like most sexual species, the sex ratio in humans is close to 1:1. In humans, the natural ratio between males and females at birth is slightly biased towards the male sex, being estimated to be about 1.05 or 1.06 or within a narrow range from 1.03 to 1.06 males/per female born.

Detailed explanation-2: -The sex ratio is the ratio of males to females in a population.

Detailed explanation-3: -A sex ratio is the ratio of males to females in a population. As explained by Fisher’s principle, for evolutionary reasons this is typically about 1:1 in species which reproduce sexually. However, many species deviate from an even sex ratio, either periodically or permanently.

Detailed explanation-4: -Complete Answer: The number of females in the population per 1, 000 males is considered the sex ratio. The sex ratio is the percentage of males to females in a population. The ratio appears to be 1:1 in most animals that reproduce sexually. This trend is clarified by Fisher’s theory.
