The earlier geneticists considered a gene to be the smallest unit (a bead or a chromomere) on a chromosome which could be distinguished as a functional unit, or as a unit of recombination, or as a unit of mutation. It was also believed that […]

Concept of Gene Conversion | Genetics
Article Shared by
In this article we will discuss about the concept of gene conversion. In eukaryotes reciprocal exchange between loci almost always produces reciprocal recombinants. In Neurospora the linear arrangement of ascospores in the ascus indicates directly which strands have exchanged segments during crossing over. Thus after meiosis in a heterozygote Aa, due to reciprocal exchange the […]

The nucleotide sequence of a gene may be translated into a complete polypeptide chain. Then a part of the same sequence may also code […]
