Weinberg's Phenotypes

In the 19th century, naturalist Charles Darwin formulated his theory of evolution. He also stated that the offspring of parents had mixtures of physical characteristics taken from the parents. This was proved incorrect by Gregor Mendel who discovered that offspring received particles from their parents that made up their physical traits. In 1908, German physician Wilhelm Weinberg found a way to connect evolution to genetic probability through the use of a formula. That same year, only six months later, English mathematician G.H. Hardy came up with the same formula and ideas. Neither of the men were aware of the other's works. In the past, it was known most as Hardy's Law because Hardy published his works in English, while Weinberg's was only
A person's genotypes is their genes, which make up their DNA. Alleles are the types of genes, come in pairs in a gene, and are responsible for a person's phenotypes(Wanjie 29). Phenotypes are the physical characteristics of a person. Alleles are either characterized as dominant or recessive. The dominant allele presides over the recessive allele, making the recessive allele "hidden". Because the recessive allele is covered, that person's phenotype will only show the dominant allele. If a person has both recessive alleles, then that person will show the recessive allele. For example, blue eyes are recessive to brown eyes. A person that has two alleles for brown eyes will definitely have brown eyes. If a person has one allele for blue eyes and one for brown eyes, then that person will have brown eyes because the brown eye allele is dominant over the blue eye allele. If a person has two blue eye alleles, then that person will have blue
Most of the time, only two genes are represented, therefore the equation has two variables. The variable p represents the frequency of the dominant allele, while the variable q represents the frequency of the recessive allele. In the Hardy Weinberg equation, p+q must always equal 1. Given the statement: You will have the dominant allele or the recessive allele. In probability, "or" means to add, therefore p+q=1. You have two alleles, thus given the previous statement, you have (p+q) and (p+q). "And" means to multiply, therefore (p+q)(p+q)=1,
