Answer:
C. CGA-UUA-CUA
Explanation:
The deoxyribonucleic acid (DNA) is a double helix molecule which is composed of four letters or 'nucleotides': guanine (G), cytosine (C), adenine (A) and thymine (T). The base-pair rules state that in the DNA double helix, G always pairs with C, while A always pairs with T. Moreover, during transcription, a base named uracil (U) replaces T in the resulting RNA sequence. Therefore, in this case, the complementary sequence (i.e., antisense strand) to the mRNA sequence is CGA-UUA-CUA.
alleles may be codominant—i.e., neither acts as dominant or recessive. An example is the human ABO blood system; persons with type AB blood have one allele for A and one for B. (Persons with neither are type O.)

Answer:
12%
Explanation:
The genes E/e and F/f are 24 cM apart.
- E_: elongated wings
- ee: small wings
- F_: five stripes
- ff: four stripes
A distance of 24 cM means that the frequency of recombination between the two genes is 24%.
The cross Ef/eF x ef/ef would produce the following offspring:
- Ef/ef: Parental; elongated wings and four stripes
- eF/ef: Parental; small wings and five stripes
- EF/ef: Recombinant; elongated wings and five stripes
- ef/ef: Recombinant; small wings and four stripes
The total percentage of recombinant gametes is 24%, and there are two possible recombinant gametes, so each of them appears in 12% of the cases.
The individuals with elongated wings and five stripes have the recombinant genotype EF/ef, therefore the percentage of the offspring with this phenotype is 12%.
