As what I read from the book, I learn that inheritance is the process by which an offspring cell or organism becomes predisposed to characteristics of its parent cell or organism. As the book says, if both homologous chromosomes in an organism have the same allele at a given gene locus, the organism is said to be homozygous, and if two homolohous chromosomes have different alleles at a given gene locus, the organism is heterozygous. The similarities and differences between parents and their children have been a source of much attention and speculation through the times. It was thought that inherited characteristics were transmitted to a new generation through the blood from both parents. We now know that equal numbers of chromosomes from each parent are combined during fertilization. These chromosomes carry the units of inheritance called the genes.
The process of inharitance itself was found by Gregor Mendel long before DNA, chromosomes, or meiosis had been discovered. Mendel......
