Structural Variations in Chromosomes | Genetics

The following point highlight the five main types of structural variation in chromosomes. The types are: 1. Deletion or Deficiency 2. Duplications 3. Translocations 4. Inversions 5. B-Chromosomes. Type # 1. Deletion or Deficiency: A deficiency means deletion of a small portion of a chromosome resulting in loss of one or more genes. A deficiency originates from breakage occurring at [...]

Translocation in Humans | Genetics

In this article we will discuss about the translocation in humans. Interchanges are the most common structural chromosome changes reported in human. Partial sterility in interchange heterozygotes is infrequent due to the production of balanced gametes and as a result, interchanges in human are identifiable only through the analysis of karyotype, usually coupled with chromosome banding patterns. Various kinds of [...]

Top 8 Aspects of Reciprocal Translocations | Genetics

The following points highlight the top eight aspects of reciprocal translocation in genetics. The aspects are: 1. Chromosome Pairing 2. Orientation of the Quadruple at Ml 3. Sterility in Interchange Heterozygotes 4. Crossing Over in the Interchange Heterozygotes 5. Detection of Interchanges 6. Isolation of Homozygous Interchange Lines and a few others. Aspects of Reciprocal Translocations Chromosome Pairing Orientation of [...]
