Extended Data Fig. 2: K-mer frequency estimates genome size and Hybrid clonality.
From: Hybridization and low-light adaptability in California eelgrass (Zostera spp.)
Illumina short reads produce K-mer frequency histograms for (a) Z. marina accession Zmar913-Mar3, (b) Z. pacifica accession Zpac1022-Sio2 and (c) Hybrid accession Zmar1102-1A. Peak 1 indicates the heterozygous peak (K-mer coverage at max. frequency used to estimate diploid genome size) and 2 the homozygous peak (estimates haploid genome size). Twelve Hybrid plants from Mariner’s Basin (d) demonstrate homogenous K-mer content at the homozygous and heterozygous peaks, indicating that all individuals are clones. SET d = 1 indicates K-mers found in only one individual in the set, 1<d < 12 some shared individuals but not all, and d = 12 all individuals.
