Overview of topic

Each creature has a diverse set of characteristics, such as height, skin colour, and so on. In an individual, each character is represented by two-unit components called alleles that share the same gene locus on the two homologous chromosomes. Mendel experimented with hybridization for seven years, and based on his findings, Correns developed the three principles of inheritance: Law of Dominance, Law of Segregation, and Law of Independent Assortment.

    In the monastery garden, Mendel began his plant hybridization experiments with garden peas (Pisum sativum) in 1856. Based on his findings, he created the Law of Segregation, which demonstrated clear-cut changes in morphological features by segregating a single gene during inheritance. The garden pea (Pisum sativum), which he utilized in his trials, helped him succeed by providing a number of benefits. He coined the terms “dominant trait” and “recessive trait” to describe the tall character that dominated and was evident in the F1 generation, and “latent trait” to describe the dwarf character that existed in a hidden (latent) form in the F1 generation.

    A genuine pure breeding tall pea plant (TT) and a true pure breeding dwarf pea plant (DD) were crossed by Mendel (tt).

    Because all of the kids in the F1 generation were tall, the hybrids have dominant characters (Tt). This demonstrated that tallness had the upper hand over dwarfism. When he allowed the two F1 hybrids (Tt) to self-cross, he got a diversity of plants in the F2 generation (TT, Tt, tT, tt) in a 3:1 ratio. In the F2 progeny, tall and dwarf plants are found in the ratio of 3 tall plants (TT, Tt, tT) to 1 dwarf plant (tt).
