If a deed is held in joint tenancy, when one of the tenents dies, the others remain on the deed and they are equal owners. The property will then pass to the last surviving tenants heirs, either by Will, Trust or by intestate succession. The children of the tenant who did before the others do not take in the property.
In joint tenancy, the children of the deceased do not take the interest - it gets allocated to the other owners. In the case of a married couple, the surviving spouse would then own the entire property by operation of law (automatically). If the survivor then wishes to sell, typically they would need to submit the death certificate to the title company in lieu of that person's signature. When the surviving spouse passes, the estate would then pass through the surviving spouse's heirs - which may or may not be the same children (assuming intestate succession).
