As explained by fisher's principle, for evolutionary reasons this is usually about equal in species which reproduce sexually [1][2] however, many species deviate from an even sex ratio, either periodically or permanently. The ratio of males to females in a population is called the sex ratio, and it can have a pretty big impact on society as a whole The sex ratio, at its broadest, applies to any species with. These operational definitions are straightforward when individuals are unisexual (gonochorism in animals Dioecy in plants) but in cosexual individuals (e.g., hermaphroditic plants), the allocation of resources to different sex functions (e.g., sperm vs
Eggs) defines the sex ratios. The sex ratio is usually expressed as the number of males per 100 females It may also be given as a percentage excess or deficit of males.the gender ratio is a pretty important part of evolutionary life Sex ratio calculation is used to describe the balance between the male and female population. Other articles where sex ratio is discussed A second important structural aspect of populations is the relative numbers of males and females who compose it
The sex ratio is an important characteristic that helps us to study the population of a given area For example, when we say that the sex ratio in india is 960, it means that there are 960 girls for every 1000 boys.
