According to Mendel, the genotype is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of heredity are the genes or factor..

Physical Basis of Heredity - According to Mendel, the genotype is made of certain structures called factors. The factors controlled the inheritance of all traits. These factors are present in pairs. The factors are now called genes. Thus the physical basis of heredity ..

Summary - All these evidences point to the fact that evolution occurs. The exact mechanism of evolution, however, is not yet conclusively proven. But constant study and research in the above fields is continuing for answers. Asexual reproduction results in identical offspring whereas sexual reprodu..

Summary - Heredity may be defined as the transmission of characteristics through generations Variation may be defined as differences among individuals of a species Both heredity and variation play important roles in evolution of organisms The study of the mechanism of transmissi..

Question: What is the physical basis of heredity? What are alleles? Answer: Genes are the physical basis of heredity. The different expressions of the same genes are called allele..

(or gene flow) Some beetles with brown genes could have immigrated from another population, or some beetles carrying green genes could have emigrated. ..

The rediscovery of Mendelism and the subsequent idea of chromosomal basis of inheritance, paved way for several significant discoveries in the field of heredity. Many other patterns of inheritance which cannot be explained on the basis of Mendel's laws alone, were discovered in plant and ..

Beetles with brown genes escaped predation as their colour became one with the environment and they remained as if hidden. In the process they survived to reproduce more frequently than beetles with green genes. This allowed more brown genes to go into the next genera..

Formation of Polynucleotide Each DNA molecule has two such polynucleotide chains joined to each other by hydrogen bonds. The hydrogen bonds are between the nitrogenous bases of the opposite nucleotides. If the polynucleotide chains are the sides of the ladder, the bonds can be compared to the rungs..
