Genes and alleles are genetic sequences, and both determine biological traits. So, what makes them different?
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 ...
Which factor(s) can prevent permanent fixation of an allele (i.e. maintain genetic diversity)? a. Genetic drift b. Gene flow c. Natural selection d. Mutation What are fixed alleles, and how do they affect the population? Give ...
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 ...
Genes come in multiple forms or versions. Each of these forms is called an allele. For example, the gene responsible for the hair color trait has many alleles: an allele for brown hair, an allele for blonde hair, an allele for red hair, and so on. ...
Some alleles are dominant. These show up in an organism's phenotype no matter if it is homozygous or heterozygous. For example, in humans, broad eyebrows, long eyelashes and dimples are dominant traits. Recessive traits appear when an organism has inherited two recessive alleles for a particular...
combination of alleles and genes present in organisms makes up their genotypes. Phenotypes, on the other hand, are the actual observable forms of the traits. Two alleles on a gene may determine that an individual has blue eyes; the alleles compose the genotype and the blue color is the ...
the number of nucleotides in the repeated unit is the same for the majority of the repeats within an individual microsatellite locus, but the number of repeats for a specific locus may differ, resulting in alleles of varying length, which can be analy...
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...
