What is a Mitochondria | Genetics

In this article we will discuss about the meaning of mitochondria. Mitochondria are cytoplasmic organelles containing their own DNA and some enzymes that catalyse the process of oxidative phosphorylation. Mitochondria are not autonomous bodies because they require their own genes and nuclear genes to function normally. The role of mitochondria in cytoplasmic inheritance was first understood when Ephrussi and his [...]

Determination of Chi-Square Test | Genetics

For determining chi-square or goodness of fit, the size of the population must be considered. Suppose in one cross of tall and dwarf plants, out of the 100 plants of F2, 70 are tall and 30 dwarf instead of 75 and 25 as expected from a 3: 1 ratio. Obviously there is a deviation of 5 from the normal. In [...]

Structure of Chlamydomonas (With Diagram) | Genetics

In this article we will discuss about the structure of chlamydomonas (explained with labelled diagram). The unicellular green alga Chlamydomonas is haploid with a single nucleus, a chloroplast and several mitochondria (Fig. 9.3). It can reproduce asexually as well as sexually by fusion of gametes of opposite mating types (mt+ and mt-). The mating type is controlled by a single [...]
