Learn about dominance hierarchy, agonistic behavior, and territoriality in animal societies. Discover examples, pros, and cons of the three social...
Endogamy is used for a number of reasons, such as to accumulate wealth, maintain family claims, reinforce geographical boundaries, and enforce the dominance of a social class. Endogamy often leads to a smaller gene pool, which can lead to genetic diseases from a lack of genetic variation. ...
What is speciation in biology? What are the two main types of genetic drift? What are single-allele traits? What are polygenic traits in biology? Explain the different types of natural selection. What is inheritance in biology? What is the principle of dominance in biology? What is a multipl...
What two aspects of climate are key to characterizing a biome? What are biomes and how are they influenced by latitude and elevation? Give Examples List the two biomes that are dominated by grasses. What are the abiotic factors that control the dominance of grasses in these biomes? Where is...
An accurate delineation of MyHC-based fibre types was obtained with the immunohistochemical method developed. This protocol showed a high sensitivity and objectivity to delineate hybrid fibres with overwhelming dominance of one MyHC isoform and, furthermore, it allowed a semiquantitative delineation of ...
We often associate high testosterone levels with male dominance and aggression. However, in ruffs—aspeciesof shorebird that breeds across Europe and Asia—some males face a unique challenge: they produce excessive testosterone. Researchers at theMax Planck Institute for Biological ...
Arabidopsis thaliana, regeneration, light, dominance, explants, f1 hybrids, ecotypesWe have compared regeneration proficiency for cultured explants from different tissues of different ecotypes of Arabidopsis thaliana. Proficiency varies widely with both tissue and ecotype, and is......
