Genetics Mendel's studies of the nature of inheritance in plants. In his paper ""Versuche über Pflanzenhybriden"" ("Experiments on Plant Hybridization"), presented in 1865 to the "Naturforschender Verein" (Society for Research in Nature) in Brünn, Mendel traced the inheritance patterns of certain traits in pea plants and described them mathematically. Although this pattern of inheritance could only be observed for a few traits, Mendel's work suggested that heredity was particulate, not acquired, and that the inheritance patterns of many traits could be explained through simple rules and ratios. The importance of Mendel's work did not gain wide understanding until 1900, after his
Molecular genetics Molecular genetics Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level and thus employs methods of both molecular biology and genetics. The study of chromosomes and gene expression of an organism can give insight into heredity, genetic variation, and mutations. This is useful in the study of developmental biology and in understanding and treating genetic diseases. Gene amplification is a procedure in which a certain gene or DNA sequence is replicated many times in a process called DNA replication. In separation and detection, DNA and mRNA are isolated from cells
