Another explanation for the neoteny in domesticated animals can be the selection for certain behavioral characteristics. Behavior is linked to genetics which therefore means that when a behavioral trait is selected for, a physical trait may also be selected for due to mechanisms like linkage disequilibrium. Often, juvenile behaviors are ...
However, humans also have relatively large noses and long legs, both peramorphic (not neotenic) traits, though these peramorphic traits separating modern humans from extant chimpanzees were present in Homo erectus to an even higher degree than in Homo sapiens, which means general neoteny is valid for the H. erectus to H. sapiens transition ...
SPECIAL is an acronym statistics system developed specifically for the Fallout series, representing the seven attributes used to define Fallout characters: Strength, Perception, Endurance, Charisma, Intelligence, Agility and Luck. SPECIAL is heavily based on GURPS, [12] which was originally intended to be the character system used in the game.
A phenotypic trait is an obvious, observable, and measurable characteristic of an organism; it is the expression of genes in an observable way. An example of a phenotypic trait is a specific hair color or eye color. Underlying genes, that make up the genotype, determine the hair color, but the hair color observed is the phenotype.
In these games and their sequels, the player assumes the role of a Trainer whose goal is to capture and use the creatures' special abilities to combat other Pokémon. Some Pokémon can transform into stronger species through a process called evolution via various means, such as exposure to specific items. [ 3 ]
Traits that evolve during contest competition, such as large body size and physical aggression, are often costly to produce and maintain. [90] These traits may therefore be indicators of male genetic quality and/or ability to provide resources and other direct benefits. [ 90 ]
[1] [2] The term covers the organism's morphology (physical form and structure), its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior. [ citation needed ] An organism's phenotype results from two basic factors: the expression of an organism's genetic code (its genotype ) and the ...
Four different traits can be identified by pedigree chart analysis: autosomal dominant, autosomal recessive, x-linked, or y-linked. Partial penetrance can be shown and calculated from pedigrees. Penetrance is the percentage expressed frequency with which individuals of a given genotype manifest at least some degree of a specific mutant ...
