WebPhenotype is often largely a product of genotype (the alleles, or gene versions, the organism carries). When a phenotype produced by certain alleles helps organisms survive and … WebA phenotype is the physical description. For instance, for the genotype Aa (where "A" is the allele for having tall fur and "a" is the allele for having short fur, the phenotype would be tall fur, because A is dominant over a. Incomplete dominance is when the 2 alleles combine to create and intermediate or blended phenotype.

WebThese factors may be genetic, environmental, or both. Polygenic inheritance. Some characteristics are polygenic, meaning that they’re controlled by a number of different genes. In polygenic inheritance, traits often form a phenotypic spectrum rather than falling into clear-cut categories. Environmental effects. WebHow can mutations affect organisms? Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal. northland eye specialists
