Other examples of incomplete dominance are: Note that in case of straight hair heterogeneous genes, Ss, the result will vary. A cross between straight hair genes (homogeneous, SS) and curly hair genes (homogeneous, ss) will result in wavy hair (heterogeneous, Ss). An example of incomplete dominance in humans is that of wavy hair. The result is always an intermediate between the two alleles. Incomplete Dominance is the phenomenon which is exhibited when the dominant and recessive alleles blend to give a particular phenotype. In a similar fashion, a person carrying I B and I O alleles will express blood group B. An individual having allele I A and I O will express blood group A. It is important to understand that alleles I A and I B are dominant over I O. In other words, both A and B co-dominates to give AB blood group (the body will produce both A and B antigens). Here both the alleles will express without masking each otherР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s effects. An individual carrying I A and I B alleles, will have AB blood group. These alleles result in four blood groups- A, B, AB, and O.

There are 3 alleles for human blood groups, I A, I B and I O. A classic example of such an occurrence is the human blood group. Other factors like co-dominance and incomplete dominance also affect the expression of certain traits.Р В РІР‚СњР вЂ™Р’В¬o-dominance is the phenomenon wherein both the dominant and recessive allele expresses themselves in the same individual. These are also called the Mendelian inheritance as they follow the inheritance pattern as observed by Mendel in his inheritance experiments. Therefore, it will result in any of the two forms, with no intermediate results. These are those traits that are governed by a single gene, having two alleles. List of Dominant and Recessive Human Traits Single Gene Traits This can be deduced from the following table: Similarly, if the father is tall with genes Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTtР В Р вЂ Р В РІР‚С™Р РЋРЎС™ and mother is also tall with genes Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTtР В Р вЂ Р В РІР‚С™Р РЋРЎС™, then their progenies will have the following genes Р В Р вЂ Р В РІР‚С™Р Р†Р вЂљРЎС™ Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTTР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (tall), Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTtР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (tall) and Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўttР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (dwarf). It can be deduced from the following table: In the same example, if we consider a father who is tall with genes Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTTР В Р вЂ Р В РІР‚С™Р РЋРЎС™ and a mother who is dwarf with genes Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўttР В Р вЂ Р В РІР‚С™Р РЋРЎС™, then their progenies will have tall heights with genes Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTtР В Р вЂ Р В РІР‚С™Р РЋРЎС™. And the gene for dwarfism will be Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўttР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (presence of two copies of the allele). If Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTР В Р вЂ Р В РІР‚С™Р РЋРЎС™ is the allele for tall height and Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўtР В Р вЂ Р В РІР‚С™Р РЋРЎС™ is the allele for dwarfism, then the gene for tall height will be Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTTР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (presence of two copies of the same allele) or Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўTtР В Р вЂ Р В РІР‚С™Р РЋРЎС™ (presence of one copy of the allele). Let us understand this by a simple example. However, recessive traits are those that are expressed only when two copies of an allele are present in the gene. Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. The interaction between these alleles determines the expression of a gene. These two or more variations or forms of genes are called alleles. Thus, some of our physical traits are similar to our mother while some match with our fatherР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s traits. These include one copy of the gene from the mother and one copy from the father. There are two copies of each gene present in an individualР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s body with the exception of eggs and sperms. However, they do not just govern our outer appearance but other features like resistance to certain diseases, intolerance to certain chemicals, etc.

Such features include our height, skin color, eye color, hair texture, etc. These features are what makes us look the way we do.

They code for specific proteins that are responsible for various physical features. One of the most important principles that governs life is inheritance of genes. Such varied physical features that you like or dislike are a result of not only the corresponding genes but their expressions too! What are the Dominant and Recessive Traits?
