Thanks, Jupit3r-- Actually, it's a lot more interesting for me to interact with someone who is avidly learning astrology-- and reading (gasp, shock!) actual books on the subject! For so many astro-learners, if it's not on the Internet, they're not interested.
There's a lot here, but just to start with a few chart patterns....
A yod is basically two quincunxes jointed by a sextile. A quincunx on its own gives annoyance or uncertainty. There is an issue, but it doesn't demand resolution or some kind of manifestation the way a square would. The sextile helps to link the quincunxes together, in a way that generates some ease and delight (3-series) but with a desire to manifest (2-series.) I think a sextile suggests excitement. If a 4th planet opposes the apex planet, this strengthens the configuration.
With the baby boomers and beyond, everyone ended up with a Neptune-Pluto sextile, so we would view that as generational, not personal, unless personal planets are involved.
In your case, we get the moon as one apex planet; and Uranus (possibly Neptune) as the other one, with the IC involved. One reading of the moon is Mom. Uranus conjunct the IC would suggest to me some instability in your early home life. Neptune has a "now you see it, now you don't" quality to it: it may be that you did not feel grounded or secure as a child.
In traditional astrology, the IC and 4th house indicated Dad and the paternal inheritance. Mom (as Dad's wife, a 7th house matter) was then counted as 7 houses from the 4th, or the MC and 10th house. Modern astrologers often like to match up signs and houses, so they reversed the order, assigning the 4th house to Cancer >>>Moon>>>Mom; and the 10th house to Dad.
I suggest you simply look for the best fit. Either way, the 4th house and IC seem to relate to one's early childhood conditioning and ancestry.
The more I think about your chart and the kinds of questions you've been asking, the more I think you might wish to conduct a serious study of your family history (ruler of the 5th house of hobbies in the 4th house of ancestors, in heritage-oriented Capricorn.) This study should not only reveal some interesting information about your biological father, but you might wish to go back further in time. Fortunately there is so much data now on-line, notably at the Mormons' (Church of Jesus Christ of Latter-day Saints) family history archives.
If your grandparents are living, you might wish to start by interviewing them. Possibly your biological paternal grandparents are living. Do they know about you? A good reason to learn more about your bio-dad is that if he had any hereditary health conditions, it's best if you know about them.
Part of the reason why I say that you might enjoy family history is your 12th house sun. One way to learn about oneself is through a study of your roots. In the traditional "house of self-undoing," however, it is hard for the ego to develop a firm sense of identity in the 12th. The 12th seems to indicate things hidden from us, although possibly apparent to others.
I wonder if you are trying to trick or do an end-run around the identity issue by studying astrology. There is nothing wrong with that (at least, it's how I got into astrology) but with the sun in Virgo the 12th house, at some level the 12th house asks its solar natives to give up the effort, and to focus on being helpful (Virgo) to others.
Although the quest for a firm identity may ultimately prove illusory, you will learn an awful lot in the process. The journey is its own reward.
