The gene D controls wing shape in flies and has two alleles: D is wild-type and dominant, and d is recessive and causes flies to
borishaifa [10]

Answer:

10% of progeny would have wild type phenotype

Explanation:

True breeding fly with wild type wings and small eyes: De/De

True breeding fly with downward wings and wild type eyes: dE/dE

Cross between them :  De/De X dE/dE = De/dE ( F1 )

Recombination frequency = 20%

Next cross, De/dE X de/de =

De/de = parental = 40%

dE/de = parental = 40%

DE/de = recombinant = 10%

de/de = recombinant = 10%

The third genotype i.e. one of the recombinant genotypes will have the wild type makeup ( DE/de ) hence 10% of flies would have wild type phenotype.
