A transgenic mouse expressing a human growth hormone gene exhibits gigantism. Researchers discover a second transgenic mouse line with the same human growth hormone gene construct, yet these mice show normal growth. Which of the following is the MOST LIKELY explanation for this discrepancy?
The second mouse line has a mutation in the mouse growth hormone receptor gene.
The human growth hormone gene is not being transcribed in the second mouse line.
Position effect variegation due to the transgene's insertion site in the second mouse line.
The second mouse line expresses an endogenous inhibitor of human growth hormone.

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
