3.1 Genome survey analysis
A male shrimp (F. chinensis ) was sequenced using the Illumina
HiSeq platform, and 125.99 Gb raw data were obtained.
The K-mer analysis (Figure S1)
revealed that the genome size was 1,384.88 Mb, with 54.79% repetitive
sequences, and the genome heterozygosity was 1.04% (Table 1). The first
six comparison species using 10,000
high quality reads randomly were all homologous comparisons (Table S1),
which indicates an absence of exogenous contamination in our sample.
