Punnett Squares

Mother’s Genotype

Punnett Square – a chart used to show four possible ways that genes can be combined when passed from parents to offspring as a result of reproduction.

Father’s genotype – on side of square

Mother’s genotype – on top of square

Allele 1

Allele 2

Father’s Genotype

Allele 1

Allele 2


Punnett square example

Punnett Square – example

  • Top left box = Mother’s first allele, Father’s first allele

  • Top right box = Mother’s second allele, Father’s first allele

  • Bottom left box = Mother’s first allele, Father’s second allele

  • Bottom right box = Mother’s second allele, Father’s second allele
