Chromosome Rearrangements Flashcards
What are the 4 major types of rearrangements?
Deletion
Duplication
Inversion
Translocation
What are the subtypes of deletion rearrangements?
Terminal deletion
Interstitial deletion
What are the subtypes of duplication rearrangements?
Tandem duplication
Insertional duplication
What are the subtypes of inversion rearrangements?
Pericentric inversion
Paracentric inversion
What are the subtypes of translocation rearrangements?
Reciprocal translocation
Robertsonian translocation
What are nonallelic homologous recombinations?
CO at the wrong location so there is a chromosome rearrangement
What are unbalanced rearrangements?
Deletions are an unbalanced rearrangements
Can a person be homozygous for a deletion?
No
Can a person be heterozygous for a large deletion?
No
What are balanced rearrangements?
Inversion and translocations change the location but not the number of genes
