Inheritance of genetic traits

HSOffspring inherit their genetic traits that make them look like their parents, through  genes contained in the chromosomes during the process of reproduction.All body cells of an organism have identical genetic information,yet are different in structure and function.  The explanation for this variation in cellular structure,  is that  different  parts of the genetic  instructions areContinue reading “Inheritance of genetic traits”
