Practice question

Marker inheritance mode determines informativeness. Codominant markers allow differentiation of homozygote and heterozygote, displaying both alleles in heterozygote. Simple Sequence Repeats are multiallelic codominant, with each allele visible as distinct band length. Single Nucleotide Polymorphisms are biallelic codominant, heterozygote shows both nucleotides. RAPD, ISSR and AFLP generate dominant profiles where presence denotes dominant allele, absence recessive, preventing heterozygote distinction. RFLP is also codominant but pairing SSR with SNP represents most widely used codominant combination for linkage mapping, diversity analysis and molecular breeding applications.
