Child Genetics Lab -Baby Trait

🧬 "Whose eyes will the baby have? What blood type? How tall?"

Child Genetics Lab is a genetics simulator that takes the traits of a mother and a father and
shows you, at a glance, the proportions of traits their virtual children would have.

Pick the parents' traits, tap the button, and the app "delivers" 1,000 virtual children using
Mendelian inheritance, then tallies the proportion of each trait. From eyelid shape to blood
type to height — see intuitively how traits pass from parents to children.

▣ Great for
· Expecting parents and couples curious which traits a child might inherit
· Students learning Mendelian genetics, dominance, blood types and polygenic traits
· Biology or science class demos and presentations

▣ Features
· Enter 14 parental traits → simulate trait proportions across 1,000 virtual children
· Mendelian dominance (eyelid, dimples, freckles, earlobe, tongue-rolling, PTC taste, eye color, hair color, handedness)
· Incomplete dominance (curly/wavy/straight hair), ABO co-dominance + Rh, sex-influenced trait (baldness)
· Polygenic trait (height) with Hardy–Weinberg carrier estimation
· Trait proportion bar charts + child height distribution histogram (sons vs. daughters)
· "Draw one child" — a trait card for a single random virtual child
· Save results, compare past runs, genetics glossary
· Free, offline, Korean/English

▣ Note
· This app is an educational/entertainment simulation based on simplified genetic models.
Results are statistical approximations and do not predict or guarantee a real child's traits,
nor do they replace medical or genetic diagnosis.
