Which of the following is FALSE regarding the formation of transgenic animals?
◦ DNA is usually inserted into eggs or embryos since totipotency is not characteristic of most animal cells.
◦ Homologous recombination occurs much more frequency than illegitimate recombination.
◦ If some cells of the embryo do not receive the introduced DNA, the result is an organism with cells of different genotypes; the organism is known as a chimera.
◦ For a transgenic animal line to be produced from a chimera, the transgene must be carried by germ line or germ cells.
◦ Either integration of multiple copies of the transgene or position effect can lead to variability in the expression of the transgene.
