01 / Overview

Mendel conducted a series of pea hybridization experiments in the mid-19th century. By analyzing the traits of pea hybrid offspring, two major genetic laws, the "law of separation" and the "law of free combination," were discovered, laying the foundation of genetics and widely recognized as the "father of genetics. The law of segregation states that genetic factors that control the same trait exist in pairs, and when gametes are formed, they separate and are inherited from different gametes to offspring; The law of free combination states that the separation and combination of genetic factors that control different traits do not interfere with each other, and when forming gametes, the genetic factors that determine different traits can freely combine.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

Mendel discovered two major laws of inheritance through pea hybridization experiments: the law of segregation and the law of free combination. The law of segregation states that genetic factors that control the same trait exist in pairs, separate when gametes are formed, and are inherited separately by offspring. The law of free combination states that genetic factors of different traits can freely combine and do not interfere with each other when forming gametes. These discoveries laid the foundation for genetics.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
