WebNov 29, 2024 · Mendelian Inheritance theory was formulated by Gregor Mendel. The concept of Mendel Genetics was based on the theory of dominance. After his observations based on pea plants, he proposed two laws called the law of segregation and the law of independent assortment. The law of segregation explains that factors segregate during fertilization. Mendel always observed complete dominance of one allele over the other for all the seven characters which he studied in garden pea. Later on, cases of incomplete dominance were sported. For example, in four o’clock plant (Mirabilis jalapa) there are two types of flowers: red and white. A monohybrid cross … See more In co-dominance both alleles of a gene express their phenotype in heterozygote. Blood group antigens of man present an excellent example of co-dominance.

Now cases are known where a gene has more than two allelic forms, although only two of them can exist in a diploid cell at a time. … See more A gene that causes death of its carrier when in homozygous condition is known as lethal gene. Mendel’s findings were based on equal survival of all genotypes. In the presence of lethal genes, the normal segregation ratio of 3: … See more
