"Sex is the trait that determines whether a sexually reproducing organism produces male or female gametes."
The biological characteristics that determine whether a person is male or female.
Biological sex: Refers to the physical and chromosomal characteristics that define males and females.
Gender identity: The sense of being male, female, both, or neither, which may or may not correspond with a person's biological sex.
Sexual orientation: The pattern of romantic or sexual attraction one has to others.
Sexual health: Maintaining a positive and respectful approach to sexuality, including safe sex practices and regular testing.
Reproductive anatomy and physiology: The biological processes related to sexual reproduction, including menstruation, pregnancy, and childbirth.
Puberty: The period in which an individual goes through physical and hormonal changes that signal the onset of sexual maturity.
Consent: The presence of mutual agreement and understanding in sexual activity.
Sexual pleasure: Understanding and exploring one's sexual desires and needs for personal fulfillment.
Relationships and communication: Effective communication strategies in romantic and sexual relationships.
Sexual violence: Understanding and preventing abusive sexual behaviors that harm others.
Sexuality and social issues: The impact of cultural, social, and political factors on sexual identity and behavior.
"Male organisms produce small mobile gametes (spermatozoa, sperm, pollen), while female organisms produce larger, non-mobile gametes (ova, often called egg cells)."
"Organisms that produce both types of gametes are called hermaphrodites."
"During sexual reproduction, male and female gametes fuse to form zygotes, which develop into offspring that inherit traits from each parent."
"Males and females of a species may have physical similarities (sexual monomorphism) or differences (sexual dimorphism) that reflect various reproductive pressures on the respective sexes."
"Mate choice and sexual selection can accelerate the evolution of physical differences between the sexes."
"The terms male and female typically do not apply in sexually undifferentiated species in which the individuals are isomorphic (look the same) and the gametes are isogamous (indistinguishable in size and shape)."
"Some kinds of functional differences between gametes, such as in fungi, may be referred to as mating types."
"The sex of a living organism is determined by its genes."
"Most mammals have the XY sex-determination system, where male mammals usually carry an X and a Y chromosome (XY)."
"Female mammals usually carry two X chromosomes (XX)."
"Other chromosomal sex-determination systems in animals include the ZW system in birds, and the X0 system in insects."
"Various environmental systems include temperature-dependent sex determination in reptiles and crustaceans."
"Male organisms produce small mobile gametes (spermatozoa, sperm, pollen), while female organisms produce larger, non-mobile gametes (ova, often called egg cells)."
