1.	What will happen if an individual receives two copies of a gene from the same parent?(a) UPD(b) One gene will be automatically inactivated(c) Both the genes will show their product(d) Nothing much will be seenThis question was posed to me in class test.My doubt is from Silencing and Genomic Imprinting in portion Regulating Gene Expression in Eukaryotes of Cytogenetics
Answer» Right answer is (a) UPD Explanation: This condition gives rise to UPD or uni parental disomy. Here as the imprinting RELATION will be HAMPERED, the individual may LACK any active copy of the gene leading to DEVELOPMENTAL defects.
