Sex-related illnesses have various causes: [citation needed] Sex-linked genetic illnesses; Parts of the reproductive system that are specific to one sex; Social causes that relate to the gender role expected of that sex in a particular society; Different levels of prevention, reporting, diagnosis or treatment in each gender
Chromosomal sex is determined at the time of fertilization; a chromosome from the sperm cell, either X or Y, fuses with the X chromosome in the egg cell. Gonadal sex refers to the gonads, that is the testicles or ovaries, depending on which genes are expressed. Phenotypic sex refers to the structures of the external and internal genitalia. [6]
The neuroscience of sex differences is the study of characteristics that separate brains of different sexes. Psychological sex differences are thought by some to reflect the interaction of genes, hormones, and social learning on brain development throughout the lifespan.
The role genetics plays in the growth of a small baby into an adult has traditionally been a complex and poorly understood area of human biology.
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development.
Height measurement using a stadiometer. Human height or stature is the distance from the bottom of the feet to the top of the head in a human body, standing erect.It is measured using a stadiometer, [1] in centimetres when using the metric system or SI system, [2] [3] or feet and inches when using United States customary units or the imperial system.
[1] Genetic Discrimination is considered to have its foundations in genetic determinism and genetic essentialism, [2] and is based on the concept of genism, i.e. distinctive human characteristics and capacities are determined by genes. [3] Genetic discrimination takes different forms depending on the country and the protections that have been ...
Genetic studies of traits and populations have been used to justify social inequalities associated with race, [7] despite the fact that patterns of human variation have been shown to be mostly clinal, [8] with human genetic code being approximately 99.6% – 99.9% identical between individuals and without clear boundaries between groups.
