Kostenloser Fantasy-Genetik-Rechner für OC-Stammbäume.
Use when designing a character's family tree or a fan-fiction OC's offspring odds. Standard Mendelian inheritance — perfect for a simple visible trait.
A bare Punnett square calculator does the same math. This one wraps it in narrative trait names that suit world-builders.
Two parents combine into a Punnett square: each cell is one of four equally likely offspring genotypes (AA, Aa, aA, aa).
Aa and aA are functionally identical — both heterozygous. AA shows the trait; aa hides it; Aa shows it but carries the recessive.
Percentages are simply the count of matching outcomes divided by four.
Not yet — one trait at a time. Run the tool again with the next trait.
Standard Mendelian: A is dominant over a. Aa shows the trait; aa does not.
They show the probability that offspring inherit each genotype based on the alleles each parent can pass on. For example, two heterozygous parents yield a classic 1:2:1 genotype ratio and a 3:1 dominant-to-recessive appearance ratio.
Homozygous means both copies of the gene are the same allele (either both dominant or both recessive), while heterozygous means one of each. A heterozygous parent can pass on either allele, which is why it produces variable offspring.
