Addition of a functional gene or group of genes to a cell by gene insertion to correct an hereditary disease. The DNA sequence of a gene can be used to predict the mRNA sequence, and the genetic code can in turn be used to predict the amino acid sequence. Genetic counseling The educational process that helps individuals, couples, or families to understand genetic information and issues that may have an impact on them. Genetic engineering technologies See recombinant DNA technologies. A chromosome map showing the relative positions of the known genes on the chromosomes of a given species.
Genetic map See linkage map.
Genetic material See genome. The scientific study of heredity how particular qualities or traits are transmitted from parents to offspring. Genetic screening Testing groups of individuals to identify defective genes capable of causing hereditary conditions. A phenotypic variance of a trait in a population attributed to genetic heterogeneity. Genome maps Charts that indicate the ordered arrangement of the genes or other DNA markers within the chromosomes.
