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.
Beginning in the mid 1600's Earth entered into a mini-ice age. 1815 was known as the "year without a summer" and snow fell in many European countries during the summer months. The prolonged climate change is attributed to low sun spot activity, while the summer snow is believed to be the result of
A major volcanic eruption.
As described above, the condition will lead or cause the lung tissue to be less elastic. That being said, the lungs will be limited due to its stiffness. This will lead to decreased lung capacity as well as decreased vital capacity.

I think I'm sorry if it's wrong:(
