Punnett Squares

Master genetics! This Punnett Squares worksheet helps students grasp genotypes, phenotypes, and inheritance. Perfect for biology practice.

Match the term with the correct definition. Genotype The genes an offspring receives for a trait Phenotype The physical appearance of a trait Homozygous Dominant When a genotype has two dominant genes for a trait Heterozygous When a genotype has one dominant and one recessive gene Homozygous recessive When genotype has two recessive genes for a trait Sort the word options into the proper categories. Homozygous Dominant AA TT WW YY Heterozygous Bb Hh Gg Mm Homozygous Recessive ii ss ff zz Labeling Complete the Punnett square. Incomplete Dominance When the dominant allele does not completely mask the recessive.As a result some of the recessive trait will be observed in the phenotype.Example:The color red is dominant over the recessive color white.Pink flowers are a result of a blending of red white. Codominance When there is more than one dominant allele.As a result both alleles will be expressed in the phenotype.Ex. if both red and white alleles are dominant, both traits will be expressed in the flower.Ex. the AB blood type in humans Label Label the following examples: CODOMINANCE or INCOMPLETE DOMINANCE
