A group of scientists are studying the genome of the Drosophila Fly. In these flies, the allele for long wings is dominant over the allele for short
wings. What phenotype would a heterozygous genotype have?
A. Long wings
B. Short wings
C. LI
D. LL

A. Long wings

Explanation:

Long wings - LL or Ll

Short wings - ll

Heterozygous genotype means one dominant and one recessive allele. So, the genotype would be Ll.

Therefore, the phenotype would be long wings.

Hope that helps.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
