Punnett Square Calculator For Monohybrid And Dihybrid Crosses

This Punnett Square Calculator is designed for students, teachers and biology enthusiasts who want a fast, visual way to explore inheritance. Use the monohybrid tab when you are studying a single gene with two alleles, and the dihybrid tab when you want to see how two genes can segregate and recombine in offspring according to Mendelian genetics.

Monohybrid Punnett Square

Use this section when you want to predict offspring from a cross involving one gene with two alleles, such as A and a. Enter each parent’s genotype as a two-letter combination like AA, Aa or aa. The calculator assumes uppercase letters represent the dominant allele and lowercase letters represent the recessive allele.

This calculator uses a simple Mendelian model with one dominant allele and one recessive allele. Real-world traits can be influenced by many genes and environmental factors, so results are for educational purposes only.

Dihybrid Punnett Square

Use this section when you want to model inheritance for two genes at once, such as A/a for one trait and B/b for another. Enter each parent’s genotype as a four-letter combination like AaBb, AABB or aaBb. The calculator uses a classic Mendelian assumption of independent assortment and simple dominance for each gene.

This dihybrid tool treats the two genes as unlinked and independently assorting, which matches classic Mendelian pea plant examples. In real organisms, gene linkage, multiple alleles and non-Mendelian patterns can lead to different results.

Punnett Square Calculator Formula or Method

Punnett Square Calculator is better described by a rule sequence than by one universal algebraic equation. The tool validates the supplied values, normalizes the units or formats needed by the selected mode, applies the calculator-specific lookup, date, scoring, conversion, or conditional rules, and then formats the resulting output.
