Genetics

Mendclian law of inheritance

Linkage and interaction of genes.

Multiple alleles and isoalleses.

Linkage and crossing-over mapping of genes.

Sex determination in plants and animals: Sex-linkage, nondisjunction as a proof of chromosomal theory of inheritance.

Basic microbialgenetics: Conjugation, transformation, transduction and there use in genetic mapping.

Concept of gene: Classical and modern gene concepts, Psedoallelism, position effect, imragenic crossing over and complemention (cistron, recom and muton), benzer’s work on rll locus in T4 phage.

Mutations-spontaneous and induced: chemical and physical mutagens, induced mutations in plants, animals and microbes for economic benefit of man.

Structural and numerical aberrations involving chromosomes: evolution of wheat, cotton and rice, hereditary defeets-Kleinefelter, Turner, Cri-du-Chat and Down syndromes.

Extrachromosomal inheritance: cytoplasmic inheritance, mitochondrial and; chloroplast genetic systems (Differences between them and general concept).

Population genetics: Hardy – Weinburg equilibrium, gene and genotypic frequencies.
