Answer :
Final answer:
Female bodybuilders achieving muscle mass akin to their male counterparts illustrate manipulating sexual dimorphism influenced by behavior, exercise, and nutrition, aside from the innate hormonal controls. Their practices also show the effects of altering the typical secondary sex characteristics usually influenced by sexual selection.
Explanation:
Female bodybuilders who train to achieve physiques similar to male bodybuilders are demonstrating a concept known as sexual dimorphism, which refers to physical characteristics beyond the reproductive organs that differ between males and females of the same species. However, through intensive training and sometimes the use of supplements like steroids, females are able to develop muscle mass and physical characteristics that resemble those commonly associated with males, such as increased muscularity and decreased body fat.
In the context of biological sciences, females and males tend to display different secondary sex characteristics, such as differences in muscle size and body composition. These differences are typically influenced by hormonal variations and become notable during puberty. That said, the practice by female bodybuilders demonstrates how behavior and environmental factors, such as exercise and nutrition, can significantly influence the extent of these sexual dimorphisms.
Additionally, within the realm of sexual selection, females are typically more selective in their mating choices, often opting for males with certain desirable traits. This can lead to pronounced differences in secondary sexual traits among males. However, the phenomena exhibited by female bodybuilders show that the expression of these traits can be accentuated or minimized based on external inputs rather than strictly following genetic and hormonal predispositions.
Answer:
They demonstrate that male and female bodies are much more similar than different.
Explanation:
The condition of sexual dimorphism results in particular differences between males and females which go beyond reproductive organs.
Unlike in many other species, such as birds, human male and female representatives share more similarities than differences. This especially can be observed with individuals whose bodies are more exposed as it is with bodybuilders. Bodybuilders shape their bodies according to certain standards and goals and then demonstrate them during competition.
In humans, five characteristics separate males and females. Among them internal and external genitals, muscle mass and height, as well as the endocrine systems. All of them have a psychological effect on the individual which further manifest sexual dimorphism. Nevertheless, humans present have comparatively low presence of it.
