homozygous dominant genotype example
Effects of Homozygous Genes. Following are some examples of homozygous genes. 1  The dominant trait for eye color is brown, represented by BB. 2  All other eye colors â blue, grey, green, and hazel â are recessive traits, represented by bb.3  A homozygous brown eyed person would have the BB gene, while a homozygous blue eyed person would have the bb gene. Having dimples on the cheeks is a dominant trait, with the homozygous DD gene causing them. 2  However, the recessive trait is distinguished by the symbol dd; individuals with this homozygous gene will not have freckles. 3  Curly hair is a dominant trait, with the homozygous HH gene causing the condition.
