Ecotype - Wikipedia
WebAn 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. However, site differences seldom exert enough selection pressure to override gene flow. WebFeb 28, 2024 · QTL mapping and genome screens reveal patterns of polygenic adaptation from standing genetic variation. Ecotype-associated loci prominently include circadian … WebFeb 15, 2024 · An ecotype is a subset of a species that possesses genetic adaptation to local growing conditions. Sometimes ecotypic adaptations are visible to us as variations in shape, size, or color. Other ecotypic adaptations are not readily apparent, for example, adaptations to various soil chemistries, minimum winter temperatures, and drought … imagine 8 letters crossword clue
