Explanation:
Detailed explanation-1: -In the ecotype species concept, an ecotype is an ecologically homogeneous and genetically cohesive group of organisms whose diversity is limited by periodic selection and/or genetic drift.
Detailed explanation-2: -In an evolutionary context, ecotypes can be thought of as an early stage of speciation, potentially leading to different subspecies, or even to different species under continued isolation and selection.
Detailed explanation-3: -An ecotype is a population adapted to local site (usually edaphic) conditions that occur in patches rather than in gradients. Traditionally, within-species genetic variation is considered by most silviculturists as ecotypic.
