Juxtaposition Cross of Mutation
The Juxtaposition Cross of Mutation is a Human Design Incarnation Cross made of Gates 3, 50, 41 and 31, carried only with the 4/1 Profile. It is a fixed path of change that starts in the body: a pulse that begins things, values that decide what is kept, and a voice behind both.
Simple way to think about it: Mutation is the first crack in the ice in spring. Nothing about the lake has been decided yet, but the surface will never be one piece again, and everything underneath begins to move.

Look for the line that reads Juxtaposition Cross of Mutation. The four numbers in brackets are the Gates of your Personality Sun and Earth, then your Design Sun and Earth, for example (3/50 | 41/31). They match the four Gates below. The chart symbols guide shows where the Sun and Earth sit in the two planet columns.
The Mutation cross on the BodyGraph
Four Centers hold the four Gates, and two of them are motors. Gate 3 sits in the Sacral and Gate 50 in the Spleen; on the Design side Gate 41 is in the Root and Gate 31 in the Throat. The conscious pair, 3 and 50, is the pair the Right Angle Cross of Laws carries; the Design pair, 41 and 31, comes from the Right Angle Cross of The Unexpected.

How the Mutation cross is placed
The Mutation (3/50 | 41/31)
Ordering is your conscious Sun and Values your conscious Earth, so the beginning of things and the sense of what is worth keeping are the part you know firsthand. Contraction and Influence run on the Design side, which means the pressure to start and the voice that carries it may show to others before they show to you.
The four Gates in plain language
Start with the Gate that holds your Personality Sun, then its Earth, then the Design pair.
Gate 3: Ordering
Gate 3, Ordering, is the conscious Sun. It sits in the Sacral and its hexagram is Difficulty at the Beginning. It completes Channel 3-60 with Gate 60 in the Root, a Channel that happens to be called Mutation, in the Individual circuit and a Design of energy that fluctuates and initiates, a pulse. Its fourth line, Charisma, is fixed in this cross, so the beginnings you make draw people in. It is the only Gate here that sits in a format energy Channel, and it is the one that sets the cross going.
Gate 50: Values
Gate 50, Values, is the conscious Earth. It sits in the Spleen, an awareness Center, and its hexagram is The Cauldron. It completes Channel 27-50 with Gate 27 in the Sacral, the Channel of Preservation, in the Tribal circuit. It grounds the cross in deciding what is worth keeping and what a group stands on. Its fourth line, Corruption, is the line every Mutation chart carries, so the values come with a sharp sense of what has gone bad. That sense makes the Gate protective as well as principled.
Gate 41: Contraction
Gate 41, Contraction, is the Design Sun, lived without thinking. It sits in the Root and its hexagram is Decrease. Its Channel runs to Gate 30 in the Solar Plexus as 30-41, Recognition, which is part of the Collective circuit. The Root is the Center of pressure and the push to begin, and here that push sits beneath awareness. Its first line, Reasonableness, is fixed in this cross, so the push to begin tends to come with sensible reasons attached.
Gate 31: Influence
Gate 31, Influence, is the Design Earth and the cross's only Throat Gate. Its hexagram is Influence. Gate 7 in the G Center is its partner for 7-31, the Channel of The Alpha, a Collective circuit Channel. It grounds the cross in a voice that others follow. Its first line, Manifestation, is the line every Mutation chart carries, so the voice starts as something that makes a thing real by saying it. Whether it reaches the G Center depends on whether Gate 7 is in your chart.
A Sacral pulse in front, a Root push behind
Gate 3 is in the Sacral, the Center of life force and work, and Gate 41 is in the Root, the Center of pressure and drive. Both are motors, one on each side of the chart's awareness. The pulse that starts things is the part you know, and the push to begin sits underneath it.
Gate 3 can complete Channel 3-60 with Gate 60, which would join the Sacral to the Root directly. The cross does not include Gate 60, so the two motors are not wired to each other by the cross itself. Whether they are depends on the rest of your chart.
One Gate begins and one Gate judges
The conscious pair puts Ordering in the Sacral beside Values in the Spleen. The first gets things going and the second decides what deserves to stay. Their fixed fourth lines, Charisma and Corruption, sit close together: what draws people in, and what has gone bad.
The Spleen is an awareness Center that speaks once and in the present tense, and Gate 50 can complete Channel 27-50 with Gate 27 in the Sacral. In Mutation that means you know both the beginnings and the standards, and you can feel when a beginning is about to break one.
A cross that ends in the Throat
Gate 31 is the cross's only Throat Gate, and it sits on the Design side. The pulse, the values and the pressure are all lower in the body, and the voice is the last stop. Because it is lived without thinking, people may hear the change in you before you have said anything about it.
That gives the cross its particular timing. The start has already happened by the time you speak about it, and what you say tends to confirm a shift people have been sensing. Speak when the shift is clear, and the voice carries more than it would if it ran ahead.
Why the Mutation is a Juxtaposition cross
Mutation does not pass through different roles. The pulse that starts things remains the Sun of the cross, and the standards stay in place beneath it. Being fixed here means change is your constant, the one thing you reliably do, and the work is choosing which beginnings to follow through. The Juxtaposition goes with one Profile, 4/1. With any other Profile the same four Gates make a Left Angle cross instead.
The four lines of the Mutation cross
A Juxtaposition cross comes only with the 4/1 Profile: your Personality Sun sits in line 4 and your Design Sun in line 1, and each Earth shares the line of its Sun. So unlike every other cross, this one comes with its lines fixed. Everyone born with the Mutation cross carries these four.
| Personality Sun: Gate 3.4 Charisma | Your beginnings draw people in, and the pull of what you start often reaches others before you have explained it. |
|---|---|
| Personality Earth: Gate 50.4 Corruption | Your values come with a sharp sense of what has gone bad, and you notice rot in a group early. |
| Design Sun: Gate 41.1 Reasonableness | Below awareness the push to begin arrives with sensible reasons attached, which makes it easy to follow without checking. |
| Design Earth: Gate 31.1 Manifestation | Your voice makes things real by saying them, so a casual announcement can start something you did not plan. |
Living the Mutation cross
At work
People with Mutation are often the ones who start the thing: a project, a team, a change in how work is done. That suits founding, early-stage building, reform and creative direction. It is less comfortable in roles that only maintain. Pair yourself with someone who finishes, and say clearly which of your beginnings you intend to carry through to the end.
In relationships
In a relationship you may be the one who sets change in motion, and your partner may feel carried along. Slow the announcement down: say what you are sensing before you say what you have decided. Your standards for what is worth keeping are real, and they are easier to share when you name them early instead of letting them harden into judgment.
In decisions
A strong start is not a good decision. The Sacral pulses and the Spleen judges, but neither can tell you what is right for you.
Decide through your Type and your inner Authority, and let the cross supply the first move and the sense of what is worth keeping. Your Strategy and Authority are how you get there; the cross is where it leads.
When the Mutation cross is misread
"Mutation means my life will keep falling apart"
"Corruption means something is wrong with my values"
"It is the Left Angle Cross of Wishes"
Questions to sit with
One question for each Gate. Notice which one you answer quickly and which one you avoid.
- Gate 3: What have you started recently, and who was drawn in before you had explained it?
- Gate 50: What in your surroundings has gone bad that you have not yet named?
- Gate 41: What reasons are you giving yourself for a new beginning, and which of them are really pressure?
- Gate 31: What did you announce lightly that turned into something real?
