Document Summary

Plasticity is a basic property of phenotypes/ inevitable property of life. Phenotype = all the expressed characteristics of an organism. Genotype = complete dna sequence, not all expressed. All phenotypes depend on both never alternatives, they are always co-requisites. Variation is the raw material that enables evolution pre-existing phenotypes the genome and environment. Hence, proteins are made by gene expression. Dna sequences store information can be transcribed into rna information can be translated to make proteins, which enable life processes and affect organismal traits. Sex in an evolutionary perspective is just another reaction norm. Phenotypic plasticity : the capacity of genetically similar organisms to express different phenotypes in response to different environments. Plastic variation can be subtle or extreme, continuous or discontinuous. Plasticity can be maladaptive environments outside historical range can cause developmental disruptions or phenotype-environment mismatch. Neuroendocrine regulation (hormones) expression through life and across generations.
