The Global Genomics Market size is expected to reach $68.9 billion by 2027, rising at a market growth of 17.5% CAGR during the forecast period. A genome is an organism's genetic material. It includes genes, noncoding DNA, mitochondrial DNA, and chloroplast DNA, among other things. Genomic refers to the science and study of genomes. Because of its applicability in numerous fields of study, such as intragenomic phenomena such as epistasis, pleiotropy, heterosis, and other interactions between loci and alleles inside the genome, genomics is gaining massive traction in the market.
