They include population genetics, the study of genetic patterns within populations; classical genetics, how traits are transmitted and expressed; microbial genetics, the heredity of microorganisms; and molecular genetics, the molecular study of genes and related structures. These developments led to the deciphering of the genetic code of the DNA molecule, which in turn made possible the recombinant DNA techniques that hold immense potential for genetic engineering. However, a small number of traits are controlled by the interactions of the alleles for just one gene. Browse through all study tools. The zygote develops into the child. The physical key to heredity lies within the nucleus of the cell in structures called chromosomes. From his studies, Mendel derived certain basic laws of heredity: heritable factors do not mix but remain segregated; some factors are dominant, while others are recessive; each member of the parental generation transmits only half of its hereditary factors to each offspring; and different offspring of the same parents receive different sets of hereditary factors. This genetic code is passed on to the offsprings in both bisexual and asexual organisms. Thus, the development of a trait may be manipulated by environmental changes, and in different environments the carriers of similar genetic traits may develop and behave in different ways.
