Detailed explanation-1: -During Mendel’s time, the most accepted hypothesis of inheritance of physical characteristics was blended inheritance. The blended inheritance hypothesis suggests that physical traits (or phenotypes) of offspring are an intermediate of the parents.

Detailed explanation-2: -Charles Darwin’s theory of inheritance by pangenesis, with contributions to egg or sperm from every part of the body, implied blending inheritance.

Detailed explanation-3: -Blending Theory of Inheritance Mendel noticed plants in his own garden that weren’t a blend of the parents. For example, a tall plant and a short plant had offspring that were either tall or short but not medium in height. Observations such as these led Mendel to question the blending theory.

Detailed explanation-4: -In codominance, the phenotype is between heterozygous phenotype where the dominant allele will suppress the recessive allele. When one allele is dominant over the other offspring show blend of the parent’s trait.

Detailed explanation-5: -He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. He recognized the mathematical patterns of inheritance from one generation to the next.
