The appearance of a recessive phenotype due to deletion of dominant gene is called_______________(a) Hemi-dominance(b) Pseudo dominance(c) Imperfect dominance(d) Co-dominanceI have been asked this question during an online interview.This interesting question is from Chromosomal Abnormalities : Deletion in section Chromosomal Basis of Inheritance of Cytogenetics

Answer»

The correct CHOICE is (b) Pseudo DOMINANCE

For explanation: Pseudo dominance is the condition when the recessive allele is expressed in deletion mutation of dominant. Hemi-dominance is the condition when only one COPY of the gene is supposed to be PRESENT, as in genes of Y chromosomes. Co-dominance and imperfect dominance are different.
