Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome. An allele frequency is calculated by dividing the number of times the allele of ...

The Hardy-Weinberg Theorem deals with Mendelian genetics in the context of populations ... Natural selection is not acting on the locus in question (i.e., there are no consistent differences ...

The authors identified variants in two regions—the locus that encodes blood type and a multi-gene cluster on chromosome 3—that were linked to respiratory failure during SARS-CoV-2 infection. “We know ...

The term 'loci' is the plural of locus, which refers to a specific position of a gene on a chromosome. In the context of this study, it denotes particular locations associated with an elevated ...
