Let’s know about What is the difference between primary and secondary sex characteristics.
Primary vs. Secondary Sexual Characteristics
Although there is a considerable difference between primary and secondary sexual characteristics, many may not have thought about it. In a very brief statement, primary characters are sex organs, but secondary characteristics are sex hormones and other related functions. Therefore, there is a demand for a better understanding of primary and secondary sex characteristic.
primary sexual characteristics
A sex organ, aka the primary sex characteristic, is any bodily part of any organism associated with the reproductive system. These characteristics develop during the gestation period in an organism and male and female differentiation occurs in sexually dimorphic organisms. The Y chromosome from the father contains a special gene responsible for the determination of the testis during embryonic development; Otherwise, the gonad will develop into the ovary. Therefore, male and female primary sexual characteristics are similar in origin, but differ in finality. The external genitalia are the primary sexual characteristics, and they are the only external clue about the exact sex of any animal’s newborn. However, the sex organs do not fully function until puberty. However, without well-developed sex organs, secondary characteristics will never operate. Examples of male and female primary characteristics include penis, testicles, epididymis, prostate, scrotum, cervix, clitoris,
secondary sex characteristics
These are the characteristics of any organism capable of distinguishing a male from a female. However, these features are not entirely related to the reproductive system. Despite the undoubted importance of primary characteristics, it would be a failure without secondary sex characteristics. In the animal world, there are many examples to describe secondary sex characteristics. The male lion’s face, shiny face and rump of knots, cattle horns, and the extravagant tail feathers of peacocks are some of the prime examples of secondary features. In humans, pubic hair, genital hair, breast hair of females and facial hair of males are the major anatomical secondary features. These changes occur only after puberty, and involve complex mechanisms based on hormonal influences inside the animal’s body. Testosterone in men and estrogen in women are the main hormones responsible for the occurrence of secondary sex characteristics. In addition to physical changes,
What is the difference between primary and secondary sex characteristics?
Primary sex characteristics are the sex organs, while secondary characters are other changes in relation to the development of the organism.
The development of primary sexual characteristics begins during the embryonic development of an organism, whereas the development of secondary sex characteristics begins only around puberty.
Primary sex characteristics have a direct physical connection with the reproductive system, while secondary sex characteristics do not necessarily require physical contact with the reproductive system.
Except for the genital and reproductive systems, there is no major difference between males and females as far as primary characteristics are concerned. However, the two sexes differ in the development of secondary sex characteristics.
There are considerable behavioral and attitude differences between the two sexes with secondary sexual characteristics, while there are between males and females with fewer sexual characteristics.
