Hey!
What let us know what are non-renewable resources:
Resources which can’t be renewed again after usage , it takes millions of year to form them again
These include fossil fuels
If we go on using fossil fuels it will be empty and we will run out of it.
A energy resource like fossil fuels is an non renewable! But why? Because rate of consumption is more than the rate of formation !
To sustain them , we must adapt to using of Renewable resources like Wind energy, hydro , wind etc .
I hope it’s clear!
Have a good day :)
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.
