life before the birth of baby .
• It explain about mutation there causes of types affects on the individuals
as well as their offspring .
• It explain about blood grouping and possibilities in the next generation .
• IT explain about prenatal diagnosis test.
• Genetics explain about gene therapy its indication types and methods .
• It also explain about genetic counseling role of a nurse is genetic
counseling and its scope in prevention and treatment of same genetics
disorders.
Principles of heredity
1. Heredity is transmitted from parents to offspring as individual characters
2. Genes that may replace one another at the same locus are called as
Alleles or Allelomorphic genes.
3. Gene are link with each other on a chromosome these linkages are more
marked with near by gene.
4. The observed characters expressed by genes is called phenotype .
5. The set pattern of genes present in the cells is called genotype .
