A degradation signal could be unmasked on a normally foided cylosolic protein by A phosphorylating a proteosome B. cleaving a peptide bond on the protein.

Explanation / Answer

the allele present are ;

C - curved hair ,dominant

C+ -recessive ,straight hair

H -spiraled hair - dominant

h -recessive of spiraled

a/a+ -lack of hair { seen at third locus }

1. phenotype of the female mosquito ;

the phenotype of the female will be curved hair which is a dominant allele ,located at the first locus of the gene .

2. Genotype of the male parent ;

c+/c+ ; h/h ; a/a+ ,

c+ represent the straight hair which is a recessive allele ,a no hair , h ,recessive spiraled hair
