Mac Version Coming Soon! (in a year or two;) Now on Facebook Support the Mac Port on Patreon Linkage is a free computer-aided design program for Microsoft Windows used for prototyping of mechanical linkages. The mechanism is edited and animated in the same window allowing for quick analysis and modification while working on a design. It is simplistic for a CAD program but that is the intent. The current version is 3.16.42 Download Linkage files here including documentation and beta software ... Learn about linkage, crossing over, recombination and gene mapping in biology with examples and practice problems. Explore Morgan's experiment on Drosophila and the factors affecting linkage and recombination. When two or more characters of parents are transmitted to the offsprings of few generations such as F1, F2, F3 etc. without any recombination, they are called as the linked characters and the phenomenon is called as linkage. This is a deviation from the Mendelian principle of independent assortment. Mendel's law of independent assortment is applicable to the genes that are situated in separate chromosomes. When genes for different characters are located in the same chromosome, they are tied ... In linkage, two or more genes linked together are always inherited together in the same combination for more than two generations, whereas in recombination the genetic material is exchanged between different organisms which leads to the production of offsprings with the combination of traits. The chromosomal theory of inheritance came into existence long after Mendelian genetics. The lack of advanced technology and physical proof were two reasons for the rejection of Mendel’s concept of ...
