In adult cell cloning, the nucleus is taken out of an unfertilised egg cell from sheep P. A nucleus from a body cell of sheep Q is then put into that egg cell. The embryo produced is placed into the uterus of sheep R. Which sheep is the lamb genetically identical to?
Sheep Q only, because the nucleus of its body cell contains the DNA
Sheep P only, because the egg cell provided the cytoplasm of the cell
Sheep R only, because the lamb developed in the uterus of that sheep
Sheep P and Q, because the lamb has a nucleus and cytoplasm from both
