Guppies are born with the potential to be either male or female, but their gender is not immediately determined at birth. Unlike mammals, which have distinct sex chromosomes that determine their gender, guppies and other fish have a more complex system of sex determination that is influenced by both genetic and environmental factors.
In most cases, guppies will develop into males or females based on the ratio of males to females in their environment. If there are more males than females in the population, then some of the guppies will develop into females to help balance out the gender ratio. Conversely, if there are more females than males, some of the guppies will develop into males.
However, there are also genetic factors that can influence a guppy’s gender. Some guppies have genes that predispose them to develop into one gender or the other, regardless of the gender ratio in their environment. These genes are passed down from their parents and can be influenced by selective breeding.
Overall, the gender of a guppy is determined by a combination of genetic and environmental factors, and it is not possible to predict with certainty whether a particular guppy will develop into a male or female. However, by carefully controlling the gender ratio in their environment and selectively breeding for desired traits, fish breeders can influence the gender of their guppies and create populations with specific gender ratios and characteristics.
