Punnett square virtual lab accessed the virtual lab at: heredity how are traits passed from parents to offspring a trait is a physical characteristic such as color or size that is inherited by an offspring from its parents the genes that control a trait come in pairs, one gene from each parent. Include the results of one punnett square, showing a possible combination between alleles for the trait from the parents by filling in the genotypes according to the numbers in the square, below b, b b, bb, bb b, bb, bb e.
