Solution
The correct option is A Alleles
The alternative forms of a gene are alleles which are present at fixed locus on a chromosome. For example, T and t are two alleles of the gene of plant height that lead to tall and dwarf phenotype respectively. Heterozygotes refer to the diploid organisms having different alleles of one or more genes and thereby producing gametes of different genotypes. The genetic constitution of a cell or an organism is referred to as its genotype. Complementary genes are the non-allelic genes which have their independent effect but produce a new trait when their dominant forms are present together.Therefore, the correct answer is option A.
