Fields of Gentics

Transmission/Classical Genetics

Heredity and Variation

Cytogenetics

study the genes in the cell (particularly in the chromosome)

provide the chromosomal basis of sex determination

explain the distribution of boys and girls in the family

Molecular Genetics

investigate in detail the nature of genetic material (DNA), it’s structure, mode of replication and how it acts to produce the phenotype

Population Genetics

Observed through patterns of genetic variation in populations and changes in genetic structure through time

Animal Husbandry & Plant Breeding

to produce high yielding varieties of food crops like disease-resistant plants and varieties of cows and pigs; for domestic use

Epidemiological Genetics

for better therapy, management and prevention of recurrence of inherited disease

Eugenics

choice of partners for marriage and have an estimate of the likelihood of appearance of desirable trait

Medicolegal Genetics

to solve legal problems like dispute in paternity and exchange of babies in the hospital nursery

Genetic Counseling

for deciding abortion and planning responsible parenthood through amniocentesis

Genetic Engineering

repair of defective genes the process of manually adding new DNA to an organism
Ex. GMOs

Recombination DNA Technique and Gene Cloning

DNA fragments are cut out of their normal position in the chromosome using restriction enzymes and then inserted into other chromosomes or DNA molecules using enzymes
