From a newly fertilized mouse egg, maternal pronucleus was removed and replaced with a second paternal pronucleus. Following observations/ statements were made: (A) This will result in formation of an androgenetic embryo. (B) This will result in formation of a gynogenetic embryo. (C) The embryo will not survive beyond mid-gestation since parental genomes serve distinct complementary functions due to variable imprinting pattern. (D) The adult originating from the embryo will be a clone of the father. (E) The embryo will develop as adult but will die early due to rapid shortening of the telomeres. Which one of the following represents correct combination of above statements? (1) A, B, C (2) B, C, E (3) A and C only (4) A and E only
