Mechanism of Inheritance
Mechanism of Inheritance
Mechanism of Inheritance: If both parents help to determine the trait in the progeny, both parents must be contributing a copy of the same gene.
· Thus, each pea plant must have two sets of all genes, one inherited from each parent. So, each germ cell must have only one gene set.
· Each set of gene is present not as a single thread of DNA, but as separate independent pieces called chromosome and each cell will have two copies of each chromosome, one inherited from each parent, i.e. one from male parent and one from female parent.
When two germ cells combine, they will restore the normal number of chromosomes in the progeny, ensuring the stability of the DNA of species. Such mechanism of inheritance explains the result of Mendel’s experiments and is used by all sexually and asexually reproducing organisms

(a) According to the mechanism of Inheritance if both parents help to determine the trait in the progeny, both parents must be contributing a copy of the same gene.
