What will happen if some genes of zygote are replaced with genes of a dog?will the baby show characteristics of a dog too?
NO. Humans have 46 chromosomes (23 Pairs) and dogs have 78 (39 Pairs). If these sets of chromosomes try to cross over and create new DNA, after the 23 match up from the dog and human, the dog has an extra 16 pairs. Those 16 pairs do not just vanish. The embryo does not just get 2/3 of a dog’s traits for half its DNA. It just fails to pair and nothing happens. No new DNA, no blastocyst, no zygote, no embryo
While a “humanzee” might be theoretically possible due to the relative similarity between human and chimpanzee genetic material, every experiment which aimed to artificially produce such a creature has thus far ended in failure. The genetic material of humans and dogs is far too dissimilar for hybridization to even be theoretically possible.
