Punnett Square Example: Heterozygous Cross (Ww × Ww) Explained #117586 (License: Personal Use)

This Punnett square demonstrates a monohybrid cross between two heterozygous parents (Ww), where 'W' represents the dominant allele and 'w' the recessive allele. The four resulting genotype combinations are WW, Ww, Ww, and ww, yielding a 3:1 phenotypic ratio (dominant:recessive) and 1:2:1 genotypic ratio. It’s a foundational tool in introductory genetics education for predicting inheritance patterns.

Used in biology textbooks, online educational platforms, and classroom instruction to teach Mendelian inheritance; matches user intent for understanding how traits are passed from parents to offspring via allele combinations.
