Mendel formulated his principles of inheritance based on mendel formulated his principles of inheritance based on a detailed understanding of meiosis, fertilization, and the other chromosomal processes that are involved. observations on the outcomes of breeding experiments. the underlying processes were unknown at the time. little-known works by earlier scientists. existing knowledge of chromosomal processes that he combined with insights from his own breeding experiments.

I believe that the principles of inheritance were formulated based on observations on the outcomes of breeding experiments. The underlying processes were unknown at the time. Mendel's observations and conclusions are summarized in the following two principles or laws. The law of segregation which states that for any trait, each parent's pairing of genes (alleles) split and one gene passes passes from each parent to an offspring. The other is the law of independent assortment which states that different pairs of alleles are passed onto the offspring independently of each other.
