More than two alternate forms of a gene present on the same locus are called (i) . They are produced due to repeated (ii) of the same gene but in different directions. The well-known example is (iii) .

Options

A. `{:((i),(ii),"(iii)"),("epistatic","crossing","polydactyly"):}`
B. `{:((i),(ii),"(iii)"),("multiple alleles","mutations","human blood groups"):}`
C. `{:((i),(ii),"(iii)"),("supplementary genes","mutations","hypertrichosis"):}`
D. `{:((i),(ii),"(iii)"),("linked ","genes over","alkaptonuria"):}`

Answer

To solve the question, we need to fill in the blanks with the appropriate terms based on our understanding of genetics.

1. **Identify the first blank (i)**: The question states "More than two alternate forms of a gene present on the same locus are called (i)". In genetics, when we refer to multiple forms of a gene at the same locus, we are talking about "multiple alleles". Therefore, the answer for the first blank is:
- (i) **Multiple alleles**

2. **Identify the second blank (ii)**: The question continues, "They are produced due to repeated (ii) of the same gene but in different directions." The formation of different alleles is often due to changes in the DNA sequence of a gene, which are known as mutations. Thus, the answer for the second blank is:
- (ii) **Mutations**

3. **Identify the third blank (iii)**: The question concludes with "The well-known example is (iii)". A classic example of multiple alleles is the ABO blood group system in humans, which involves three alleles (IA, IB, and i). Therefore, the answer for the third blank is:
- (iii) **ABO blood group**

Putting it all together, the complete answer is:
- (i) Multiple alleles
- (ii) Mutations
- (iii) ABO blood group
