You have told us that we each have a unique morphogenetic field that governs much of our individual makeup, our personality as well as physical form and appearance. Yet, there are many traits that seem clearly to be from the family lineage, and seem genetic in the conventional scientific sense, giving rise to offspring with a strong physical resemblance to one parent in particular, or having some characteristics of both. Do morphogenetic field influences from both parents somehow combine with the morphogenetic field of the incoming soul to impinge on the developing embryo? Is that combining done in the light?

Here you have added yet another important piece to the puzzle of how humans come to be with all the wonders of inheritance, even though scientifically, it still defies explanation. It is indeed the case that the characteristics coming from the parental lineages have an opportunity to converge, combine, and impart changes to the individual morphogenetic field of the incoming soul’s extension. This is done in the light prior to its influence on the embryo so that everything is ready from the earliest stage to begin orchestrating the development of the new human being in the womb. So this is a product of consultation by the incoming soul and the family to be the new beneficiaries of the newly arriving member of the clan, so to speak. As you have reasoned out already in your thinking, there are great advantages in having offspring that bear some resemblance to one or both parents. With this being a general theme and expected, in fact, by the parents prior to birth, it is a kind of reward, so the parents can rightfully take pride in their decision to move forward with having a family and being rewarded with children who, by resembling them, will be seen as fitting in and truly belonging to them in a deep sense. This is very much an innate characteristic, that people do prize and respect those things that resemble themselves. This is a basic safety consideration, because one is more generally safer with one's clan than outsiders. So this has deep historical and karmic roots as well, but it is also the case that the building of a strong love bond will be aided in having offspring with shared characteristics that will be seen as not only acceptable but desirable by the parents. It simply makes their children more lovable, and while that is a kind of bias, it is a bias that contributes to bonding and stability of the family unit, which is the basic foundation for successful human existence in the physical plane. You need to stick together to survive, given the challenges of the physical world and the vulnerability of depending on a physical body. That is why premium is put on the characteristics of the physical body and its appearance, because that is what is most visible to others. So someone who is tall, well-built, well muscled, physically attractive, and having characteristics appealing to the opposite sex, has a built-in advantage wherever they go in being more readily accepted and respected and even seen as desirable, whether it is applying for a job, looking for a potential life partner, or just seeking friendship. So, in a sense, an unborn child is coming in as a stranger even though a welcome one in most cases. So everything that appears acceptable to the parents that is visible will be an asset in building a strong love bond and family unit.
