Sexual dimorphism is a term for the genotypic and phenotypic differences between males and females of the same species. Through the process of meiosis and fertilization (with rare exceptions), each individual is created with zero or one Y-chromosome.
How many biological differences are there between male and female?
Men and women have practically the same set of about 20,000 genes. The only physical difference in their genetic make up is in the sex chromosomes. Only males have a Y chromosome. Although the X chromosome is present in both sexes, there are two copies in females and only one in males.
What is the difference between male and female body?
Body composition differs between men and women. Men have more lean mass, and women have more fat mass than men. Men are more likely to accumulate adipose tissue around the trunk and abdomen, whereas women usually accumulate adipose tissue around the hips and thighs.
What is the biological theory of gender?
The biological approach suggests there is no distinction between sex & gender, thus biological sex creates gendered behavior. Gender is determined by two biological factors: hormones and chromosomes.
What are the similarities and differences between the male and female hormones?
Hormones represent what makes females different from males. Generally, females and males have the same hormones (i.e., estrogens, progesterone, and testosterone), but their production sites, their blood concentrations, and their interactions with different organs, systems, and apparatus are different .
What are 5 differences between female and male skeletons?
The male skeleton is heavier and possesses a narrow pelvic cavity, broader shoulders, and long rib cage. On the other hand, the female skeleton is less heavy and possesses a wider pelvic cavity, narrow shoulders, and a shorter rib cage.
Why do the behaviors of males and females differ?

How do biological factors influence gender identity?
Biological factors that may influence gender identity include pre- and post-natal hormone levels and genetic makeup. Social factors include ideas regarding gender roles conveyed by family, authority figures, mass media, and other influential people in a child’s life.
What is the biological theory?
Biological Theory is devoted to theoretical advances in the fields of evolution and cognition with an emphasis on the conceptual integration afforded by evolutionary and developmental approaches.
What is the difference between male and female muscles?
Male skeletal muscles are generally faster and have higher maximum power output than female muscles. Conversely, during repeated contractions, female muscles are generally more fatigue resistant and recover faster.
Are there psychological differences between males and females?
Taking this approach, the researchers actually found gender differences for every one of the 10 aspects of personality that they looked at – women scored higher, on average, on enthusiasm, compassion, politeness, orderliness, volatility, withdrawal, and openness, while men scored higher on assertiveness, …
Which bone is different in males and females?

What are male characteristics?
Traits traditionally viewed as masculine in Western society include strength, courage, independence, leadership, and assertiveness.
What are some biological factors?
Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender.
How do biological factors affect behavior?
A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth.
What is biological basis of behavior?
The Biological Basis of Behavior Program (BBB) is an interdisciplinary major in which students explore biological, psychological, computational and clinical approaches to understand the nervous system as the biological basis of behavior, as well as perception, memory, motivation, and emotion.
What is an example of biological psychology?
An example of the biological approach to psychology would be the fear response. The fear response gives way to fight, flight, or freeze behaviors. Which course of action an individual takes in the presence of a stressor relies on their biological make-up.
How many bones do females have?
The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs.
Why are females more flexible than males?
Oestrogen receptors are known to be present in fibroblasts of tendon and ligaments and are believed to have a stimulating effect on fibroblast proliferation and collagen synthesis. This allows women to have increased flexibility over men. The weight distribution of our bodies is very different between women and men.
How much stronger are males than females?
It’s already known that males’ upper bodies, on average, have 75% more muscle mass and 90% more strength than females’.
How many muscles do females have?
There are about 600 muscles in the human body.
What is the difference between male and female ribs?
The Adam and Eve story has led some people to believe that men have one fewer rib than women. This isn’t true. The vast majority of people have 12 sets, or 24 ribs, no matter their sex. People born with certain conditions may have too many or too few ribs.
What is the difference between male and female pelvis?
The pelvis is one of the most useful skeletal elements for differentiating between males and females. Female pelves are larger and wider than male pelves and have a rounder pelvic inlet. Male iliac crests are higher than females, causing their false pelves to look taller and narrower.
