Above is an example of a Punnett Square for an individual with brown eyes (heterozygous) and an individual who has brown eyes (homozygous). Two common examples. Punnett Square. A variation on incomplete dominance is codominance, in which both alleles for the same characteristic are simultaneously expressed in the heterozygote. An example of multiple alleles is the ABO blood-type system in humans. In Mendelian inheritance a trait is produced by the dominant allele. The Mendelian principle illustrated in the Punnett box for one autosomal gene with incomplete dominance is the law of segregation. Snapdragon flowers (pictured) show incomplete dominance in the color of their petals. For instance, suppose you were asked to calculate the frequency of the recessive class not for an Aa x Aa cross, not for an AaBb x AaBb cross, but for an AaBbCcDdEe x AaBbCcDdEe cross.

A person with hemophilia may have severe, even life-threatening, bleeding from just a small cut. , Define the term testcross. This means that both traits can be expressed in the same regions, resulting a blending of two phenotypes. From punnett square in the offspring we have genotype ratio and probability: 1(25%)GG : 2(50%)Gg : 1(25%)gg - this typical genotypes ratio (1:2:1) for a monohybrid cross. A species of flowers exhibits incomplete dominance between the allele for red flowers and the allele for white flowers. A heterozygous person would show only mild.
