Fig. 1.
Frequency of (A) apomixis inferred from the presence of the female-apomeiosis marker allele of APOLLO and (B) linkage of male- and female-apomeiosis marker alleles across Boechera species. Here, the term “linkage” refers to the cooccurrence or coabsence of both apomictic alleles from the UPGRADE2 and APOLLO genes per individual accession.
