Dominant and recessive are an important part of genetics. They tell us if a gene is passed on and if it will be seen in the next generation. If you have a tall and short allele and the tall gene is dominant then you will be tall. This is because the dominant gene or the tall gene over rules the recessive short gene. Basically, the dominant gene is the gene that will determine what trait a person has and the recessive gene doesn't do anything against the dominant gene but it will still be passed on throughout generations. In this case the only way to be short is if you have TWO recessive short genes and no dominant tall gene.
Mendel stated in his Law of Segregation, each organism has two genes for each trait. The different forms of a gene are called alleles. If both alleles are are identical, the organism is said to be homozygous for that trait. For instance, Mendel's purebred tall plants possessed two tall alleles and are said to be homozygous tall. Likewise, a purebred short plant has two short alleles and is said to be homozygous short
If the two alleles are different, the plant is said to be a hybrid or heterozygous for that trait. As Mendel noted, when both alleles are present, one allele masks or hides the other. The stronger allele is said to dominant, and the weaker allele that is masked is said to be recessive.
When expressing dominant and recessive alleles, the dominant allele is always written as a capitalized letter, and the recessive allele as the same letter, but lower case.
