The above traits are exhibited from one’s appearance.
People with freckles have inherited at least a pair of freckles dominant gene and those without have inherited 2 freckles recessive genes.
Therefore, the curly hair gene is dominant, and straight hair gene is recessive. Parents with curly hair tend to have children with curly hair. For this reason, most people inherit the dominant gene making them right handed.Ĭurly hair is mostly determined by genes and less by environment. In most cases, the right handedness gene is dominant while left handedness gene is recessive. This shows which hand you prefer using during activities such as throwing a ball or writing. Therefore, people who have dimples express a dominant gene for dimples and those without dimples have a recessive dimple gene. This means people with dimples normally have children with dimples. The tiny, natural indentations seen on the cheeks are mostly heritable. Individuals with a cleft chin have a dominant gene while those who do not have a recessive gene. Those who are unable to do this have the recessive tongue rolling gene. If you are able to raise the sides of your tongue together, then you have inherited the dominant gene. Those with unattached earlobes have the unattached earlobe gene as the dominant gene and the attached earlobe as the recessive gene. People have their ear lobes either attached to the sides of their heads or hanging free. If your right thumb crosses your left thumb, then you have a pair of the recessive genes. If your left thumb crosses your right thumb, this means you have inherited one or two of the dominant allele. When you are interlocking your fingers, observe your thumbs. This one in dominant and recessive traits list is common. If you are able to bend your 5 th finger (pinkie) inwards towards the 4 th finger, it means you have the dominant version of the gene responsible for the distal segment of the finger to bend.
However, if an individual has 2 recessive genes, he will have a straight hair line. The peak will also be expressed if one of the alleles is widow’s peak. If the 2 widow’s alleles are present, the individual will have a peak. The gene contains 2 alleles: one for straight hairline, which is recessive and the other for widow’s peak, which is dominant. You can deduce that from the table below:ĭominant and Recessive Traits List 1． Widow’s PeakĪlso known as mid-digital, hairline is a result of expression of the hairline gene. The gene for dwarfism will then be “tt” that is 2 copies of the same allele.įor example, a tall father with “TT” genes and a dwarf mother with “tt” genes will have a tall offspring with “Tt” genes. Following this, the tall height gene will be “TT” that is 2 copies of a similar allele or “Tt” that is a copy of each allele. For this reason, the dominant versions will always win over the weaker ones.įor better understanding, let’s say “T” represents the tall height allele and “t” represents dwarfism allele. The stronger versions are referred to as dominant while the weaker ones are called recessive. There are those that are stronger than others. However, not all gene copies are the same. In this way, you have 2 copies of your eye color genes. Therefore, you have 2 copies of most of the genes you have. You might have each gene from each parent. For example, the color of your eyes is determined by eye color genes. Each gene has its own contribution to the characteristic. In some cases, a couple of genes have to work together to bring out one trait. A good example is your hair color, which is determined by a single gene that contains instructions about it. Each gene contains specific information that makes up a part of you.

It is an instruction manual only that instructions are in the form of genes. Your DNA is responsible for who you are, how you act and even how you look. Follow the dominant and recessive traits list in this article, and you will know more secrets about genetics.

Do you wish to have your mom’s dimples that she obviously passed on to your sister? Do you have your grandmother’s pimple free face and your sister has ever complained of her oily skin? Or does your father have blue eyes, but only your cousin has them in your family and not you? The cause of these varying features is not only because of corresponding genes, but also how they express themselves.
