Use the following information for the next four Questions. For a certain gene in a diploid organism, different units of protein correspond to various levels of functionality in a phenotype. Each wild type allele produces 15 units, and protein production is incremented in whole numbers. In relation to a null mutation, the wild-type allele is: Haploinsufficient Haplosufficient Neither (a) nor (b) Not enough information to determine In relation to a null mutation, the wild-type allele is: Codominant Dominant Incompletely dominant Recessive 12. In relation to a mutation that produces 5 units of proteins, the wild-type allele is: a. Codominant b. Dominant c. Incompletely dominant Recessive In relation to a mutation that produces 10 units of proteins, the wild-type allele is: Codominant Dominant Incompletely dominant Recessive

Solution

10. Haploinsufficient.

Haploinsufficiency is often caused by a loss-of-function mutation, in which having only one copy of the wild-type allele is not sufficient to produce the wild-type phenotype.

Due to null mutation, the wild type allele has become non functional and single functional allele is not functional to produce wild type phenotype.

2. Recessive.

Due to null mutation, the wild type allele is unable to produce its normal gene product and normal phenotype. Therefore it cannot be dominat, codominant or incompetely dominant.

3. Incompletely dominant.

Due to mutation, the wild type allele is producing lesser amount of gene product and is although producing a phenotype but is not fully expressed therefore is incompletely dominant.

4. Incompletely dominant.

This is also the same scenario. The wild type allele shows its expression , but not fully so incompleeltley dominant.
