Answer:
A. VG = 80
B. Broad sense heritability = 0.80
C. Narrow sense heritability = 0.30
D. Average yield = 430 Units
Explanation:
A. Given that
VA = 30
VD = 50
VI = assumed not available 
Therefore
Total genetic variance (VG) = VA + VD
 = 30 + 50
= 80
VG = 80
B. Given that
VP = 100
VG = 80
Broad sense heritability, H2 = VG/VP
= 80/100
= 0.80
C. Given that
VA = 30
VP = 100
Narrow sense heritability, h2 = VA/VP
=30/100
= 0.30
D. The difference in selection = 500 - 400
 = 100
Recall, 
Selection response is heritability multiplied by selection differential.
That is 
R = h2S
Selection differential = 100
Heritability h2 = 0.30
Selection response = 0.30 × 100
= 30units
Therefore, expected average yield = 400 + 30 
= 430 Units
 
        
             
        
        
        
That is called Urogenital myiasis which is a parasitic infestation. These flies are in the Diptera species group and the cause of this myiasis is from the eggs and larvae of this species (fly).
