单倍体基因型
单倍型（haplotype）是单倍体基因型的简称。指一条染色体上一组连锁紧密的多个 SNP 等位位点，这些 SNP 位点在连锁不平衡的作用下倾向于共同遗传。
A haplotype is a physical grouping of genomic variants (or polymorphisms) that tend to be inherited together. A specific haplotype typically reflects a unique combination of variants that reside near each other on a chromosome.
如果说 SNP 是一个核苷酸的突变，那么单倍型就是一串核苷酸的突变。
