Summary |
Features
A male means, in biology in species sexual and anisogamy , the sex that produces gametes smaller, which are then called sperm. He opposes this gender female , which produces the larger gamete called ova. Thus, individuals carrying the eggs during the embryonic development of the hippocampus are males, because their gametes are smaller.
The male organs of animals or plants are able to fertilize or organs to prepare the fertilization of females.
In animals, the male is often either at the time of reproduction, or his life or after sexual maturity size and body size and color different from the female, it is called sexual dimorphism
Genetic Characteristics
In the human and many other mammals , the male is often characterized by the pair of sex chromosomes XY.
Metazoa
The sperm produced by a testis of an individual male will fertilize the egg produced by the individual female that will turn into embryo which will then give birth to a young person directly (sometimes passing through a stage larvae ) in species viviparous or through an egg laid in species oviparous. In some species, including fish , fertilization occurs in the environment, the fertilized eggs are not carried by the female.
Linguistics
Among the most familiar species, the male and female are often referred to by different names: it was so, the bull and cow , the boar and sow , the ram and the sheep , the rooster and the hen , etc.. In less familiar species used the adjectives "male" and "female" to distinguish the two sexes; example: a mole (male or female), a hedgehog (male or female), the name of the species may also be either masculine or feminine.
Male as an adjective characterizes the organs and functions related to reproduction and the male sex. It is used both in zoology in botany.
Representation
The conventional symbol of the male is most often associated with the god and the planet Mars : .
