Incomplete Dominance and Codominance Patterns
Incomplete Dominance Pattern • a gene inheritance pattern in which neither allele is dominant so the alleles blend together – neither allele is completely dominant nor completely recessive • two alleles result in three phenotypes
Incomplete Dominance Pattern • heterozygous individuals have a phenotype somewhere in the middle of the two alleles • Example in humans – a straight-haired parent and a curly-haired parent will produce a wavy-haired child • use superscript lowercase letters to show different alleles – Hs = straight, Hc = curly • Hs. Hs = straight, Hs. Hc = wavy, Hc. Hc = curly

Codominance Pattern Is this how it works? ? ?
Codominance Pattern • a gene inheritance pattern in which a trait in a heterozygous individual has two phenotypes expressed simultaneously – both alleles are dominant • two alleles result in three phenotypes • heterozygous individuals have both alleles visible in their phenotype • Example in humans – AB blood type
Codominance in Camellia Flowers CW CW C RC R C RC W
Codominance in Shorthorn Cattle CW CW C RC R CW CR
Codominance Pattern • use superscript capital letters to show different alleles – CW = white, CR = red • CWCW = white, CRCR = red, CWCR = roan
