Overall, our observations suggest that mutation does not generate equal variance in all directions of phenotypic space or in each sex, and that pervasive variation in ontogeny or aging within a cohort could affect the variation available to evolution....
The environment refers to the broader ecological context in which an individual exists, interacts, and adapts [1], and may have direct and indirect effects on mental health [2]. It can be broadly divided into the ‘macroenvironment’, encompassing environmental characteristics at the neighbourhood ...
What is directional selection? How does the environment affect directional selection? What happens to variation in allele frequencies between populations when migration is occurring? What is the difference between spontaneous and induced mutations and their effects?
How can migration and gene flow affect a population? What happens if two genes are on the same autosome? How does the environment impact phenotype? How is autosomal DNA passed down? Explore our homework questions and answers library Search ...
Explain How Genetic And Environmental Factors Affect Phenotypes Both genetic and environmental factors affect your phenotype. Traits that are primarily attributed to genetics are height, weight, eye color, hair color, and hair texture. All traits are influenced by the environment to some extent. While...
Assessment of the impact of variation in chloroplast and mitochondrial DNA (collectively termed the plasmotype) on plant phenotypes is challenging due to the difficulty in separating their effect from nuclear-derived variation (the nucleotype). Haploid-inducer lines can be used as efficient plasmotype...
in the in utero environment; furthermore, at the time of mating, the seminal fluid can also have an impact on the in utero environment [165]. Genetic predisposition is a confounder factor in studying epigenetic changes, as inherited genetic variants can affect the baseline epigenetic landscape. ...
Doctors aren’t sure. One answer may be that IC is not one disease, but many. Different phenotypes of IC patients may have different causative factors for their bladder symptoms and this leads to differing experiences with food. The number of years one has had the disease and whether or not...
phenotypes. However, host social behavior also influences the distribution of parasites among hosts, with implications for their evolution through non-random mating, gene flow, and genetic drift, and thus ability to respond to that selection. Here, we review the paucity of empirical studies on ...
How does environmental selection affect phenotypes? 1. Why do genetic mutations happen? 2. What factors do they depend on? What is the difference between a sex-influenced gene and a gene that exhibits genomic imprinting? Define mutation as it relates to genes. Explai...
