Answer:

a rat with rabbit hemoglobin genes

Explanation:

When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.

This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.

Thus by transferring to  rat ( the DNA for Hb) as the  rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.

Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been  modified to  add certain  vitamins to improve the nutritional values.

Genetically modified bananas as edible vaccines are another example
