Experientia Aims and scope Submit manuscript

Summary

Crosses betweenMicroseris pygmaea (10 pappus parts per fruit) andM. bigelovii (5 pappus parts) have revealed 10-determining genes that additively determine the average number of pappus parts in the hybrids. One or two such genes are found in different populations. Two independent duplications of the original 10-determining gene seem to have occurred.
