RECIPROCAL TRANSLOCATIONS

• Reciprocal translocations are of two types,
  • Homozygous translocations
  • Heterozygous translocations

Homozygous translocations

• In which both the homologous chromosomes exchange parts with the two homologues of another pair.
• These are difficult to detect cytologically, since they have normal meiosis.
• Generally they can influence the phenotype, if the translocated genes have position effects, since after translocation they form linkage groups different from what they had before.

Heterozygous translocations

• Are those involving only one member of each of the two homologous pairs.
• These are detected cytologically by characteristic configurations they make at synopsis.
