Autosomal dominant A 50/50 chance of inheritance. Sickle-cell disease is inherited in the autosomal recessive pattern. When both parents have sickle-cell trait (carrier), a child has a 25% chance of sickle-cell disease (red icon), 25% do not carry any sickle-cell alleles (blue icon), and 50% have the heterozygous (carrier) condition.

Human physical appearance – Look, outward phenotype Phenotype – Composite of the organism's observable characteristics or traits; List of human positions – Physical configurations of the human body; Human skeleton – Internal framework of the human body; Sex differences in humans – Difference between males and females
A person's physical characteristics can signal cues to fertility and health, [14] [15] [16] with statistical modeling studies showing that the facial shape variables that reflect aspects of physiological health, including body fat and blood pressure, also influence observers' perceptions of health. [17]
The changes that constitute acquired characteristics can have many manifestations and degrees of visibility, but they all have one thing in common. They change a facet of a living organism's function or structure after birth. For example: The muscles acquired by a bodybuilder through physical training and diet. The loss of a limb due to an injury.
The physical attractiveness stereotype was first formally observed in a study done by Karen Dion, Ellen Berscheid, and Elaine Walster in 1972. [1] The goal of this study was to determine whether physical attractiveness affected how individuals were perceived, specifically whether they were perceived to have more socially desirable personality traits and quality of life.
Trait theory suggests that some natural behaviours may give someone an advantage in a position of leadership. [2] There are two approaches to define traits: as internal causal properties or as purely descriptive summaries. The internal causal definition states that traits influence our behaviours, leading us to do things in line with that trait.
The physical traits used to distinguish chicken breeds are size, plumage color, comb type, skin color, number of toes, amount of feathering, egg color, and place of origin. [1] They are also roughly divided by primary use, whether for eggs, meat, or ornamental purposes, and with some considered to be dual-purpose.
[8] [22] Other research using indigenous approaches to traits has taken place in countries such as India, Korea, and Greece. [8] A Chinese factor analysis of traits in 2009 found seven factors (three or four of which resembled Big Five traits). A similar study in Spain in 1997 found seven Spanish personality factors.
