WebIf the second allele is functional, the cell switches its OR expression. If the second allele is a pseudogene (as exemplified in Fig. 5B), it becomes scheme 1 and the cell reenters the selection process until another functional allele becomes both epigenetically and transcriptionally activated. We observed this type of switching rarely in WT ... WebSince human cells carry two copies of each chromosome they have two versions of each gene.These different versions of a gene are called alleles.; Alleles can be either dominant or recessive.; Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous).For example, the allele for brown eyes is …

WebFixation occurs when one allele becomes the only allele for a gene in a population, meaning that all other alleles for that gene have been lost. This statement is true.
