Several major ideas about evolution came together in the population genetics of the early 20th century to form the modern synthesis, including genetic variation, natural selection, and particulate inheritance. [1] This ended the eclipse of Darwinism and supplanted a variety of non-Darwinian theories of evolution.
Precondition for the example: Two parent dogs (P-generation) are homozygous for two different genetic traits. In each case one parent has the dominant, one the recessive allele. Their offsprings in the F 1-generation are heterozygous at both loci and show the dominant traits in their phenotypes according to the law of dominance and uniformity.
In the period 1961 – 1967, through work in several different labs, the nature of the genetic code was determined (e.g. [31]). In 1972, Walter Fiers and his team at the University of Ghent were the first to determine the sequence of a gene: the gene for bacteriophage MS2 coat protein. [ 32 ]
Although the Moravian monk Gregor Mendel, the father of modern genetics, was a contemporary of Darwin's, his work lay in obscurity, only being rediscovered in 1900. [35] With the early 20th-century integration of evolution with Mendel's laws of inheritance, the so-called modern synthesis , scientists generally came to accept natural selection.
Genomics is an interdisciplinary field of molecular biology focusing on the structure, function, evolution, mapping, and editing of genomes.A genome is an organism's complete set of DNA, including all of its genes as well as its hierarchical, three-dimensional structural configuration.
The following outline is provided as an overview of and topical guide to genetics: . Genetics – science of genes, heredity, and variation in living organisms. [1] [2] Genetics deals with the molecular structure and function of genes, and gene behavior in context of a cell or organism (e.g. dominance and epigenetics), patterns of inheritance from parent to offspring, and gene distribution ...
1913: Alfred Sturtevant makes the first genetic map, [15] showing that chromosomes contain linearly arranged genes. 1918: Ronald Fisher publishes "The Correlation Between Relatives on the Supposition of Mendelian Inheritance" the modern synthesis of genetics and evolutionary biology starts.
