Detailed explanation-1: -The three laws of inheritance proposed by Mendel include: Law of Dominance. Law of Segregation. Law of Independent Assortment.
Detailed explanation-2: -The way in which traits are passed from one generation to the next-and sometimes skip generations-was first explained by Gregor Mendel. By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed.
Detailed explanation-3: -The third law stated by Mendel is as follows – The segregation of the allele pair into two daughter cells during the second stage of meiosis division does not affect the way in which the other allele pair gets separated or segregated.
Detailed explanation-4: -Mendel’s law of dominance states that: “When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.” Law of dominance is known as the first law of inheritance.
