What are the Dominant and Recessive Traits in Humans?
One of the most important principles that governs life is inheritance of genes. There are over 200 traits that are transmitted from generation to generation in humans. These interesting aspects of human genetics are known as hereditary traits. These hereditary traits include the dominant and recessive traits in humans. Most of the genes are transmitted in the Mendelian pattern and a few are transmitted through the non-Mendelian pattern that includes: co-dominance, sex-linked genes and polygenes. You can read more on list of genetic disorders. The physical traits are those that are expressed and what makes every individual an ‘individual’. These genes reside on specific segments of the DNA. Each gene is grouped to form a chromosome and each chromosome is found in the nucleus of the cell. There are two copies of each gene present in an individual’s body with the exception of eggs and sperms. These two gene copies include one copy of the gene from the mother and one copy from the father.
