when one or single gene control more than one character?
pleiotropy
gottlieb also examined the genetic effects of single gene mutations by examining the protein expressions in the historically important round v. wrinkled isogenic pea genes examined by gregor mendel. being isogenic, these lines only differed at the r-gene locus; however, gottlieb found that approximately 10% of the proteins were different between these two lines, indicating that these single gene mutations had many pleiotropic effects. another study in peas involving genes controlling leaves, tendrils, and stipules did not find evidence of pleiotropy.

young has made major contributions to the understanding of gene control in human development and disease. he discovered that a small set of human embryonic stem cell master transcription factors form a core regulatory circuitry that controls the gene expression program of these cells. this concept of core regulatory circuitry helps guide current efforts to understand gene control, to develop reprogramming protocols for other human cell types and to understand how gene dysregulation contributes to disease.
