Punnett Squares - Complete, Incomplete, Codominance, Multiple

A Punnett Square is a diagram used to predict the genotype and phenotype combinations of a genetic cross.

Incomplete Dominance occurs when one allele is not completely dominant over another, resulting in a blended phenotype in heterozygous offspring.

Codominance is a genetic scenario where both alleles in a heterozygote are fully expressed, resulting in offspring with a phenotype that is neither dominant nor recessive.

Homozygous genotypes have two identical alleles for a trait, while Heterozygous genotypes have two different alleles.

The possible genotypes are IAIB, IAi, IBi, and ii.

The genotype of a person with type O blood is ii.

The phenotype of a person with genotype IAIB is type AB blood.

The woman's genotype must be BO.

The probability is 0%.

A dominant trait is one that will express itself in the phenotype even if only one dominant allele is present.
