What is the biological difference between male and female called?
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.
What is the biological definition of gender?
Sex is usually categorized as female or male but there is variation in the biological attributes that comprise sex and how those attributes are expressed. Gender refers to the socially constructed roles, behaviours, expressions and identities of girls, women, boys, men, and gender diverse people.
Are males and females different species?
Because of sexual reproduction, the sexes do not meet any of the criteria for a species, including interbreeding, shared common ancestry (monophyly), morphology, and spatial and temporal boundaries. Human males and females are biological subclasses of a sexual species.
Are gender roles biological?
Historically, gender roles have been largely attributed to biological differences in men and women. Although research indicates that biology plays a role in gendered behavior, the extent of its effects on gender roles is less clear. One hypothesis attributes differences in gender roles to evolution.
What is your gender identity?
Gender identity is your deeply-held inner feelings of whether you’re female or male, both, or neither. Your gender identity isn’t seen by others.

What are the male and female chromosomes?
Each person normally has one pair of sex chromosomes in each cell. The Y chromosome is present in males, who have one X and one Y chromosome, while females have two X chromosomes. Identifying genes on each chromosome is an active area of genetic research.
What are represented differently in males and females of the same species?
Sexual dimorphism is the term that refers to differences between males and females of the same species, and is most obvious as differences in external appearances. However, there can also be sexual dimorphism of internal organs and biological functions, including the immune system.

Are cells male or female?
It may surprise you to learn that — like humans — cells can be male or female. The distinction is more subtle at the cellular level, but it can actually affect how cells react in a variety of experiments. Still, many scientists don’t take into account the sex of their cells.
