11.1 The Work of Gregor Mendel Lesson Objectives Describe Mendel’s studies and conclusions about inheritance. Describe what happ
ens during segregation. Lesson Summary The Experiments of Gregor Mendel The delivery of characteristics from parents to offspring is heredity. The scientific study of heredity is genetics. Gregor Mendel founded modern genetics with his experiments on a convenient model system, pea plants:
Answer: During segregation,there is separation of two coexisting alleles for a specific trait at the point of meiosis in an individual,such that each gamete receives only one of two alleles.Alleles recombine during random fertilization of gametes when zygote is formed.
Explanation:
Gregor Mendel laid foundation of classical genetics by formulating his law i.e LAW OF SEGREGATION.He performed a series of experiments on pea plants.he focused on 7 of their traits.He proposed that such traits were determined by particular factors he termed "ELEMENTEN". these factors carrying hereditary information were transmitted from parents to offspring through gametes .He inferred that factors of pair of alleles separate from each other during gamete formation so that each gamete got only one allele for each trait.Fertilization was random.MENDEL compared results of all the 7 separately studied characters and found them similar to formulate his law of segregation as stated above !
The crepitus is a common sign of bone fracture and it's heard when the fractured surfaces of two broken bones rub together. Also If there is a severe jaw fracture, the patient might experience limited ability to move the jaw or be unable to move it at all.
