The allele combination at a gene locus is known as an organism’s –. The DNA – is then transcribed to produce –, using the DNA as a template. The resultant molecule is then transferred to the – where it is used as a template to construct –, which are responsible for producing the organism’s –.

Explanation:

The allele combination at a gene locus is known as an organism's genotype, which after expression define the phenotype of that organism.

Th sequence of nucleotide in the DNA then transcribed to produce mRNA by RNA polymerase. Then mRNA exported into the cytoplasm and works as template for the  synthesis of protein. This protein defines the phenotype of that organism.

the answer is sex-linked recessive.
