WebMay 26, 2016 · Alleles are different forms of same gene. Genes are linearly arranged on chromosomes. Chromosomes contain genetic material of cell i.e. DNA. So chemically alleles, genes, chromosomes are all DNA ! WebThe alternative allele is not necessarily the minor allele and it may, or may not, be linked to a phenotype. There can be more than one alternative allele per variant. What is linkage disequilibrium? In the genome, alleles at variants close together on the same chromosome tend to occur together more often than is expected by chance.
