Option : Supplementary gene are the genes which include two pairs of non-allelic genes. Both of them are involved in affecting the same character. Out of the non-allelic genes, one gene is dominant and can express by itself. Second gene is also dominant but expresses only when it is supported by the presence of the first gene.
Option : Complementary gene are the genes which include two pairs of nonallelic dominant genes, which interact to produce only one phenotypic trait but neither of them produces the trait in the absence of other. The presence of both of the genes is necessary for the development of dominant character.
Option : Duplicate genes are the two pairs of genes, which determine same or nearly same phenotype.
Option : Holandric inheritance is the inheritance of genes on the Y chromosome. Because only males normally have Y chromosomes, Y-linked gene scan only be transmitted from father to son. It takes place only by males.
