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

When restraining a horse for a routine veterinary procedure, it's appropriate for the veterinary assistant to Hold the horse's lead rope.
Holding the horse's lead rope is necessary, when restraining a horse for a routine veterinary procedure by the veterinary assistant.
Always hold the lead rope in the right hand by coiling the excess rope on the hand in the other hand.
Lead the left shoulder of the horse with the assistant's right hand with the excess of rope in the left hand of the assistant to avoid serious injury when the horse decides to bolt.
It becomes important to stable the horse by calming the horse before the routine veterinary procedure.
A leather band should be used in the rope by being tightened behind the legs of the front and by further fastening.
Remember not to harm the back of the horse by excessive fastening.
