Define haploid, diploid, somatic cells, germline, and gametes . Haploid- represented as ‘n’, one set of chromosomes present in gametes Diploid- represented as ‘2n’, two sets of chromosomes present in gametes Somatic cells- normal body cells, diploid in human cells Germline cells- sex cells, haploid Gametes- sperm and egg 3.
