A transgenic animal is created by inserting a gene for enhanced muscle growth into its genome. However, the resulting offspring show a variety of phenotypes, some with significantly enhanced muscle growth, others with moderate enhancement, and some with no change at all. Which phenomenon is MOST likely responsible for this phenotypic variation?
Incomplete penetrance of the transgene
Pleiotropic effects of the transgene
Variable transgene copy number and integration sites
Epigenetic silencing of the transgene in some individuals

In cloning of cattle, a fertilized egg is taken out of the mother’s womb and
The egg is divided into four pairs of cells, which are implanted into the womb of other cows
In the eight cell stage, cells are separated and cultured until small embryos are formed, which are implanted into the womb of other cows
In the eight cell stage, the individual cells are separated under electrical field for further development in culture media
From this upto eight identical twins can be produced
