Dominant-Recessive Trait Punnett Square Calculator

Understanding Dominant-Recessive Traits with Punnett Squares

Our Dominant-Recessive Trait Punnett Square Calculator makes it easy to predict genetic outcomes based on the combination of alleles from both parents. This tool helps you visualize how dominant and recessive traits pass from generation to generation, which is a fundamental concept in Mendelian genetics. Learn more about heredity and traits on our official website.

How to Use the Calculator

Simply enter the alleles of Parent 1 and Parent 2 (e.g. AA, Aa, or aa). The calculator will generate a Punnett Square showing all possible combinations of alleles in the offspring, helping you understand the probabilities of different genotypes and phenotypes.

What Are Dominant and Recessive Traits?

A dominant trait is expressed when at least one dominant allele (e.g. A) is present. A recessive trait is expressed only when both alleles are recessive (e.g. aa). For example, if brown eyes (B) are dominant and blue eyes (b) are recessive, a Bb genotype results in brown eyes.

FAQs About Dominant-Recessive Traits

What is a heterozygous genotype?

A heterozygous genotype has one dominant and one recessive allele (e.g. Aa).

Can two dominant parents produce a recessive offspring?

Yes, if both parents are heterozygous (Aa), there’s a 25% chance their child could be recessive (aa).

How accurate are Punnett Squares?

Punnett Squares show probabilities, not certainties. Real-life outcomes can vary due to complex genetics.
