All known cockatiel mutations — sex-linked, autosomal recessive, and dominant. Results are split by male and female offspring with accurate probabilities.
🔵 Sex-linked (Z-linked) mutations: Males (ZZ) need 2 copies to show the mutation. Females (ZW) only need 1 copy — they cannot be split/het for sex-linked genes. Click once for Split (males only) · twice for Visual.
🔴 Autosomal recessive: Click once for Split/Het · twice for Visual. Both sexes follow the same inheritance rules.
⚠️ Important: Results are shown separately for male and female offspring because sex-linked mutations behave differently. Always check which sex you are assigning each parent — incorrect sex selection will give wrong results.
