Gregor Mendel was the father of modern genetics. He used cross pollination to make them breed. The result was a plant that had some of the traits to two plants. This is called heredity. Heredity is the passing of genetic traits from parent to offspring. Mendel only studied one characteristic at a time. He would mix plants wiht different traits, like talll and short and purple and white. there are two different kinds of traits dominant and recessive traits. The dominant trait is the one that appears the most. The recessive trait is the trait that doesn't appears the most.
Genes affect the traits of offspring. An organism's appearance is its phenotype. Both inherited allelels form an organisms genotype. An allele is the alternative form of a gene that governs a characteristic, such as hair color. A plant with two dominant or two recessive alleles is called homozygous. A plant that has one dominant and one recessive allele is called heterozygous. A punnet square is used to organize all of the possible combinations of offspring to particular parents. PP is homozygous dominant. Pp is heterozygous dominant. pp is homozygous recessive. When the alleles are different, such as Pp, the offspring are equally likely to recieve either allele. There is a 50% chance. It's probability which is the likelihood that a possible future event will occur in any given time of the event.
Since Mendel's discoveries, reseachers have found that sometimes one trait is not completely dominant over another. This is known as incomplete dominance. If a red flower and a white flower mated you would get a pink flower.
