What are the types of dominant and recessive alleles in heredity? Are dominant characteristics always more frequent in a population than recessive characteristics? Why or why not? What are polygenic traits? How are dominant and recessive traits (alleles) defined?
What is gene inheritance in terms of dominant, recessive, sex-linked, and polygenic traits? What are examples of selective breeding? Give an example of a trait shared by members of an ingroup that is not shared by the outgroup? State the trait, the ingroup and the outgroup. This can be...

Interestingly, many traits that are supposedly one-gene, ormonogenic, traits (like eye color or the curvature of your thumb) are not. Instead, they arepolygenic, controlled by multiple genes. In our PN population sample, we included some multi-generational data: grandparents, parents and children...

Obesity and type 2 diabetes mellitus (T2DM) are rapidly growing worldwide epidemics with major health consequences. Various human-based studies have confirmed that both genetic and environmental factors (particularly high-caloric diets and sedentary life
The phenotypic level matters for the genotype–phenotype relationship As previously mentioned, traits can be measured and/or cal- culated at any level of phenotypic organization. Because trait variation is polygenic in the vast majority of cases, even for molecular phenotypes, the concepts and ...
Given the breadth of the literature on this topic, only representative examples are discussed below. The age of onset and the duration of diet are important parameters when studying the metabolic syndrome in rodents. For example, in the most commonly used obesity-prone mouse strain C57BL/6J, ...
An allele is a specific version of a gene that can influence traits, which are observable characteristics resulting from the interaction of alleles and the environment.
