PDF-Evolution at multiple loci

Linkage. A) Alleles at different loci are independent. B) Alleles at different loci are physically close to each other and on the same chromosome. C) Alternate alleles at the same locus are not independent. D) Alleles at different loci are not independent. A mechanism for change in populations..
