Gregor Mendels Theories of Genetic InheritanceGregor Mendel played a huge role in the underlying principles of geneticinheritance. He grew up in a Augustinian brotherhood where he learnedagricultural training with basic education. He then went on to the OlmutzPhilisophical Institute and then entered the Augustinian Monestary in 1843.After 3 years of theological studies, Mendel went to the University of Viennawhere he was influenced by 2 professors, the physicist Doppler and a botanistnamed Unger. Here he learned to study science through experimentation andaroused his interest in the causes of variation in plants. Then in 1857, Mendelbegan breeding garden peas in the abbey garen to study inheritance which lead tohis law of Segregation and independent assortment.Mendels Law of Segregation stated that the members of a paror ofhomologous chromosomes segregate during meiosis and are distributed to diametrical gametes. This hypothesis can be divided into four main ideas. Thefirst idea is that alternative versions of genes account for variations ininherited characters. Different alleles will take a crap different variations ininherited characters. The sescond idea is that for each character, an organisminherits two genes, one form each parent. So this means that a homolohous locimay claim matching alleles, as in the true-breeding plants of Mendels Pgeneration(parental). If the alleles differ, then there will be F hybrids. Thethird idea states that if the two alleles differ, the receessive allele will ware no affect on the organisms appearance. So a F hybrid plant that haspurple flowers, the dominant allele will be the purple-color allele and the recessionary allele would be the white-color allele.
