In this article we will discuss about the Streptomycin Resistance in Chlamydomonas. Ruthsagar (1965) has reported some cases of extrachromosomal inheritance in green alga chlamydomonas reinhardi. The alga reproduces by asexual as well as sexual means. It does not have different sexes but has positive and negative strains or mating types (mt+ and mt).

The below mentioned article provides a study note on Inheritance of Mitochondria. Introduction to the Inheritance of Mitochondria: Mitochondria are the cytoplasmic organelles which contain various respiratory enzymes and are main source of energy for the cell. They are found in cell in variable numbers. The complexity of structure of the mitochondria and their similarity in some ways to plastids [...]
In this article we will discuss about the Inheritance of Shell Coiling in Snail. One of the classical examples of intricate relationship between maternal genotype and egg cytoplasm "phenotype" was studied in snails by Sturtevant. He showed that there are two strains of water snails (limnaea peregra) that differ each other in the direction of coiling of shell. Looking into [...]
