The zygosity of loss-of-function mutations in SHELL gene. (A) Tenera palm that carried a single heterozygous mutation, only produce 1 functional copy of the gene. (B) Cis-compound heterozygous tenera palms produce 1 functional copy, when both mutations occur on the same chromosome. (C) Trans-compound heterozygous pisifera palms produce 0 functional copy, when both mutations occur on different chromosome. (D) In double heterozygous individuals, the mutations occurred in different genes.
