WebAug 18, 2024 · Plasticity-induced phenotypic novelty might instead relate to other local conditions, food resources or stressors such as predation, which as noted above are important drivers of plasticity in development and size. This would be supported, for example, if body size tended to be larger, and legs proportionately longer than trunk, in … WebIt refers to the presence in the same population of two or more alternative forms of a distinct phenotype such as flower color.

WebNov 24, 2024 · This book synthesizes an enormous amount of empirical data on hybridization both in plants and animals and argues convincingly that hybridization likely plays an important role in the origin of adaptive phenotypic novelty. Barton, N. H., and K. S. Gale. 1993. Genetic analysis of hybrid zones. WebFeb 1, 2024 · Abstract. Allopolyploidisation is a widespread phenomenon known to generate novel phenotypes by merging evolutionarily distinct parental genomes and regulatory networks in a single nucleus. The objective of this study was to investigate the transcriptional regulation associated with phenotypic novelty in coffee beans of the … WebMay 16, 2024 · Taken together, our results suggest that HE represents a major mechanism to rapidly generate novelty in genomic composition, gene expression and transcript diversity, and hence, phenotypic innovation in nascent allopolyploid plants.
