Sex Characteristics

Sexual characteristics are morphological and functional characteristics that determine the sex of an individual in the animal world. They are one of the main ways in which living organisms can reproduce and pass on their genes to offspring.

Sex characteristics can come in many forms, including physical characteristics such as body size, shape and color of skin, hair, teeth, eyes and other organs. They may also include functional characteristics, such as reproductive organs, that enable individuals to produce offspring.

In the animal kingdom, sexual characteristics play an important role in the reproduction and survival of species. For example, in many animals, males and females have different morphological characteristics, which allows them to compete for mates and select those most suitable for reproduction.

In addition, sexual characteristics can be used to determine the sex of an individual. In some cases, such as in humans, sex determination can be difficult due to the lack of obvious physical characteristics. In such cases, other methods are used, such as DNA analysis or determination of hormonal status.

Thus, sexual characteristics play a key role in animal reproduction and determination of the sex of individuals. They can appear in various forms and are used to determine reproductive abilities, as well as for the competitive selection of partners.

Sexual characteristics are morphological (external) and physiological (internal) characteristics that distinguish male and female organisms. External signs of gender are those signs that can be seen and touched, for example, the structure of the external genitalia, the presence or absence of mammary glands, and a beard in men. Inside the body, sexual characteristics appear within a few days after fertilization - through differentiation of the embryo into different tissues and organ primordia. In different organisms, the intrauterine development of female and male embryos is different, but the longer the pregnancy continues, the more difficult it is to reverse the process and preserve the female embryo. For example, in humans it is not applicable to fetuses, since the external genitalia cannot yet be determined. But gender can be diagnosed as early as 16 weeks of pregnancy. Sexual characteristics are hereditary characteristics received from parents before the birth of the child. This is one of the main reasons why gender identity can differ from desire. Despite the simplicity of gender identification for all adults, newborns and infants, there are many nuances associated with the difference between the physiology of a particular man and woman, as well as issues of health and social status in various forms of sexual orientation and gender identity. In the interest of maintaining public trust and respect, most countries around the world prohibit discrimination on the basis of gender, which manifests itself in a variety of social settings, including legal protection of human rights, forms of government and educational systems. The development of sexual characteristics does not have a single standard; it depends, as well as on the upbringing of the child, his physical form, on the acceptance of the parent, and the environment. In girls, development begins earlier than in boys; girls are often ahead of boys in development. The set of sexual characteristics is different at first, but later, as the child grows, the differences smooth out. Gender has its own social and cultural aspects
