Only some of the genes involved are recessive. Refer to the dominant and recessive page for more information on dominant genes and recessive genes. The gene that determines hair or eye color or any trait on a certain person codominance definition:
You would be pure because blue eyes and blonde hair are recessive and cannot show up if there is a dominant gene present, such as brown hair and brown eyes.

When looking at the model of inheritance which the punnett square illustrates (referred to as mendelian inheritance), you are observing combinations of dominant alleles and recessive alleles.an allele is a version of a gene (the eye color gene can consist of blue, brown, green, gray, and hazel alleles). However, if the brunette does not carry the recessive blonde trait, the baby will have brown hair.

Typical recessive traits are tallness, blonde hair, and blue eyes. Yes, a child inherits half their genes from mom and the other half from dad, but their genome is actually a veritable soup of family genetics, influenced by all the generations that came before. If a child inherits two different alleles, such as a gene for red hair and a gene for brown hair, he or she is said to be heterozygous at that allele. Blonde or red hair, which is produced with phenomelanin, is given to offspring as an allele gene. It may have been a celebrated trait because it was rare, kingsley said.
