Alleles-Examples-Basic Genetics

Traits are characteristics that may be transmitted from one generation to another. A gene is a section of DNA which has the hereditary code for the characteristic.
Genes are found in chromosomes, that are found in the nucleus of eukaryotic cells..
For each characteristic you get 1 / 2 of the info from female and half from the man parent..
Because of this you get different varieties of the same trait. These different varieties are called alleles.
Gregor Mendel, who's considered the daddy of genetics, studied 7 attributes of pea plant life.
For each characteristic he studied there were different forms of the chracteristic.
For example, the colour of the bloom could be white or crimson.
The pea plant can be tall or short
For each characteristic it had at least two different varieties of the same characteristic.
These different forms of a trait are called alleles.
Different varieties of the same characteristic.
Let’s take a look at eye color.
The trait is eye color, and the alleles are the several colors.
Another example, the shape of the chin is the characteristic, and the allele would be if it's a cleft chin smooth chin.
