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