If the host possesses any genetic powers, the resultant Brood will inherit them. The persona of the host once the Brood is "born" appears to be extinguished, but in some cases, the host's will may be strong enough to survive and coexist with the Brood's. However it is implied that hosts with advanced healing ability are unable to turn, for example when an egg was implanted in Deadpool, instead of turning into a Brood, a small Brood burst out of Deadpool's body.
