Different forms of the same gene are referred to as: Alleles

Chromosomes

Phenotypes

Spindle fibers

Alleles

Explanation:

In diploid organism, genes occur in pairs on chromosomes and such pairs are referred to as allelic pairs. An allele is an alternative form of the same gene that controls the development of a pair of contrasting genes. The genetic constitution of an organism is known as genotype while its phenotype refers to a set of observable characteristics of an organism which are an expression of an individual genotype.

The different form of the same gene are alleles.

Alleles

Explanation:

The allele are various form of gene. Some gene has the special behaviour that they present on the same locus of the chromosome and to performs different changes in the organism.

Particular humans are called as the diploid organism because it consists of two allele in our body of same locus with one gene of inherited from parent. The allele in our gene is made up of mutation occurs in the germ cells, then cell transfered into sperm or egg. Then mutated of DNA copies are copied to new cell of the growing embryo.
