What physical traits are genetically passed down from a single gene? Eye color is genetic. Eye color is also based on how much melanin you have, which determines how much color pigment is deposited in your iris. Just like skin color and hair color, our genes give us a natural color, but...

Gene (genetics) A theoretical unit of heredity of living organisms; a gene may take several values and in principle predetermines a precise trait of an organism's form (phenotype), such as hair color. Cistron (genetics) a segment of DNA that is involved in producing a polypeptide chain; ...
What determines the size of a gene? How to calculate phenotype and genotype ratios. What is the difference between genotype and phenotype? How do these two terms relate to the terms allele, homozygous, heterozygous, dominant, and recessive?
Skin Color Distribution (Photo Credit: anthro.palomar.edu) For example, the melanocortin 1 receptorgeneis what determines whether the body produces eumelanin and pheomelanin at all, and by comparing the genetics of chimpanzees and early humans, we see that this particular gene was positively selecte...
What determines the genotype of an organism? What is inheritance in biology? What is an example of a specific genetically modified organism issue? What does FOXP2 genetic mutation cause and why? What are genetic imprinting mutations? What characteristics of an organism affect gene function? What...
Inherited skin disorders such as dysplastic nevus syndrome (which causes unusual-looking moles) and ocular melanocytosis (which causes the eyelids, uvea, and nearby areas to have an unusual color) Other genetic mutations passed on to you from your parent, such as those affecting the BAP1 gene,...
Your genes dictate what color hair and eyes you’ll have how tall you’ll be as well as many other traits. Genes carry traits for plants too. By adding genes to a plant you can sometimes create new traits. For example adding a certain gene to a potato plant can make the potato plant...
Just like eye or hair color, our blood type is inherited from our parents.Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be ...
have type A blood, you have a higher risk of stomach cancer. The ABO gene has been linked to additionalcancerslike breast, prostate,liver, colorectal, lung, and cervical cancers. The connection has existed for over 60 years, and there is no explanation as to why the gene behaves this way...
