Genetics and Environmental Traits

##1. 📌 Essentials

• Species-specific characters distinguish different species; shared by all members.
• Individual characters vary among individuals within the same species.
• Hereditary characters are inherited from parents via genetic material.
• Phenotype encompasses all observable traits, influenced by genetics and environment.
• Environmental modifications (e.g., tanning) affect phenotype but are not inherited.
• Heritable traits are transmitted through DNA, unaffected by environmental changes.
• Traits like blood group are hereditary; traits like suntan are environmental.
• The distinction between heritable and non-heritable traits is crucial in genetics.
• Phenotypic changes caused by environment are temporary and non-transmissible.
• Understanding the hierarchy of characters aids in genetic and evolutionary studies.
