Phenotypic distance
Webθ = a r c c o s ( A • B A B ) The cosine of angle θ actually represents the correlation coefficient between the two vectors. As such, it exemplifies a measure of phenotypic resemblance. Possible θ values span from 0° to 180°. Small angles (i.e. close to 0˚) imply similar phenotypes. Web14. sep 2006 · Phenotypic plasticity can then be defined as a random variable, each realization being described by the absolute distance between two randomly selected individuals ( j and j ′) of the same species belonging to different environments ( i and i ′, where i is always different from i ′, as individuals were grown in different environments).

This was done for each trait reported per hybridized species pair.
Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. Populations with many similar alleles have small genetic distances. This indicates that they are … Zobraziť viac In the genome of an organism, each gene is located at a specific place called the locus for that gene. Allelic variations at these loci cause phenotypic variation within species (e.g. hair colour, eye colour).
