Sequencing 101: Ploidy, Haplotypes, and Phasing – How to Get More from Your Sequencing Data

The ploidy or number of copies of each chromosome in a genome affects not only the size but also the complexity of the genome. Geneticists often point out that a human does not have “a” genome but rather two genomes, one inherited from the mother and another from the father. The number of complete sets of chromosomes in each cell, or haplotypes, is referred to as ploidy.  Humans and most other animals are diploid (2N), having two sets. Many plants have higher ploidy, for example, the hexaploid (6N) California Redwood has 6 copies of each chromosome. The number of chromosome…
