7. Gene Interaction Flashcards
1
Q
What is gene interaction ?
A
Effect of genes at one locus depends on the presence of a gene at another loci.
2
Q
Dominant epistasis
A
when dominant allele repress action of another non allele gene.
3
Q
Recessive epistasis
A
when recessive allele repress action of one gene in homozygous condition.
4
Q
Complementation
A
two different sources of genetic information (usually, different gene loci encoding proteins or RNAs of different function) together each provide something the other lacks.
5
Q
Position effect of gene
A
effect on the expression of a gene when its location in a chromosome is changed, often by translocation
6
Q
Example of position effect of gene
A
Drosophila
