Can you mix traits from animals to humans?

Therefore could you potentially take the strength of a lion and implant it within the human genetic form?
We know you can move a muscle while both are developed and it can create uncertainty due to the possible rejection. And it's much more likely to accept if it is to develop as an embryo.

So could traits be transferred?

Technically, you can mix traits among species, which is how transgenic work is done. The first transgenic mouse was introduced with the human growth hormone gene, and by overexpressing the growth hormone, the mouse grew bigger, but not the same as human size. This is more like the function of the gene. Whether it can mix the physical features between species will be different, but something like a chimera study that mixes animals of two strains might carry physical features of both. However, between species might not be possible and could be dependent on the different embryo/fetal development of the two. If transferring the muscle from one species to another to enhance the strength is similar to transplantation, you also need to consider possible rejection, and the expected strength might not be achievable.
