Imprinting

The CA is controlled by the following buttons:
Start:  CA are planted.
Hide CA-1 Hide CA-2
Infection: Infect CA-1

The last experiments demonstrated CA fertilization . Following real fertilization some  genetic material is   silenced , or imprinted, depending from which parent it was received and other genes are activated. Here we demonstrate the activation of structure by one parent |(the sperm) 

Click on Start.  Two zygotes are planted: CA-1 (rule = 600) matures into an ovum, and CA-2 (rule = 624) into a sperm. Whenever the  CA touch each other, the sperm changes its color,  the ovum accumulates resources, and when fully mature it creates an offspring,  CA-3 (rule=3300).  which  lives for 46 states whereupon it is killed and replaced with a new one.

The sperm continues moving around the egg and  when both touch each other it replaces the CA-3 state with its own. CA2[state] --> CA-3[state]. This state generally differs from the previous states which arose from  the planted CA-3 zygote. It  initiates a new state sequence which CA-3 could not generate by itself. In other words, at this moment CA-2[state] becomes an initial state  of CA-3, which is controlled by  the rule 3300.  CA-3 lives for a while until it is replaced with a new offspring. Since CA-2 states vary, whenever it touches CA-1 a different state is transferred , and CA-3 imprinting changes.

Hide CA-1 and watch the behavior of the other CA. If the mature egg places itself beyond the applet border, click on Infection and it will return to the center. 

Reading head

When CA-2 touches CA-1, it reads its own state and stores it in CA-3. When placed under the control of rule 3300 this state  initiates a new action. Thus the CA-2 memory actually stores initiators of actions whose effect is displayed by the changing behavior of CA-3.  These actions are triggered  jointly by  CA-1 and CA-2.

Product assembly

CA-1 and CA-2 are two processes creating a product (CA-3) whose assembly takes 46 states whereupon it is shipped elsewhere. Its nature depends on:
1. Three CA rules 600, 624, 3300
2. CA resources
3. CA input and output rates.
4. The time of the CA encounter
