The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is ...

Sufferers are almost exclusively males because they only have one X chromosome and need just one recessive allele to show the condition. Only in very rare cases a female will have two recessive ...

A new study published in Life Science Alliance reveals a key genetic connection between cancer susceptibility and tissue ...

Validation of tissue-specific, maternal allele-specific methylation of the ... resource for future research into the interplay between genetics and epigenetics in disease development and progression.

demonstrating that these differences result from genomic imprinting—meaning that it is not the sequence (genetics) that matters, but rather whether the allele is inherited from the mother or the ...
