The hardy-weinberg principle is a relationship between the frequencies of alleles

If no genetic mutations will occur, then the Hardy-Weinberg principle would take place by establishing a relationship between the frequencies of alleles and the genotype of a population. In addition, the theory was said to be devised by G. H. Hardy and Wilhelm Weinberg.

100% will have that allele. Homozygous means the alleles are the same for every gamete, for example looking at Mendel's pea plants, if the allele for the trait of growing tall is T and the allele for growing short is t, a homozygous tall pea plant would have the genotype TT, meaning all of its alleles are tall
