Question
Genomic imprinting in mammals is seen in _____ percent of the genes?
100%
50-100%
25%
Less than 1%
100%
50-100%
25%
Less than 1%
Hint:
Less than 1%
The correct answer is: Less than 1%
In Autosomes most of the alleles can be expressed from both the parents, but a very short part i.e., <1% shows genomic imprinting.
Genomic imprinting, an epigenetic gene-marking phenomenon that occurs in the germline, leads to parental-origin-specific expression of a small subset of genes in mammals. Imprinting has a great impact on normal mammalian development, fetal growth, metabolism and adult behavior.
