What are multiple alleles? Relationships between alleles Alleles interact with one another and this interaction determines the phenotype of an individual. Some relationships that can exist between alleles are as follows: Complete dominance: One allele is expressed and masks the effects of the non-domin...
What is the genotype of a trait for which the two alleles an individual carries differ from each other? What are the differences of a genotype and a phenotype? What are multiple alleles? Is there dominance in multiple alleles? What does it ...
A child receives one allele for eye color from the mother and one from the father. When a child receives two alleles for brown eyes, the gene ishomozygous dominantfor that trait. If a child receives two different alleles for eye color, the gene for eye color isheterozygous. Gregor Mendel...
The long-term evolutionary trajectory of the non-recombining sex chromo- some, that is, the Y chromosome in male mammals and Drosophila, or the W chromosome in female birds and butterflies, is one of extensive genomic decay. This process leaves a signature of accumulated deleterious mutations ...
inherited two recessive alleles for a particular gene. A cleft chin is recessive, as are straight hairlines and connected eyebrows. However, not all traits follow these simple patterns. Genetics is complicated by interactions among genes, genes that affect multiple traits and influences from the ...
Allelescansometimesresultindifferentphenotypes (obser-vable traits), with certain alleles being dominant (overriding the traits of other alleles) or, in some cases, multiple alleles acting in a codominant fashion. An example of the latter is the human ABO blood group system, in which persons with...

The latter postulates that a preference for rare phenotypes is a type of selection that contributes to maintain rare alleles from being lost. This theory may, at least partly, explain the aesthetic preference we found for the rarest colors, like red and blue, and ornaments, such as long tail...
What is neomorphic allele? Neomorph allelesproduce an active product with a new, different function, something that the wild type allele doesn't do. It can be either new expression (new tissue or time) or a mutation in the product to create a new function (additional substrate or new bindi...
