1 jan 1902 ano - Chromosome Theory of Heredity Published and Meiosis further researched

Descrição:

Walter Sutton, a graduate student in E. B. Wilson's lab at Columbia University, observed that in the process of cell division, called meiosis, that produces sperm and egg cells, each sperm or egg receives only one chromosome of each type. The segregation pattern of chromosomes during meiosis matched the segregation patterns of Mendel's genes. Sutton had been observing grasshopper cells, where chromosomes have quite distinct shapes. He published his findings in 1902 and a year later, made an even stronger argument to connect Mendel's laws of heredity and the behavior of chromosomes in his paper The Chromosomes in Heredity.
