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

The correct answer is B. Hypothalamus.
Explanation
The hypothalamus is a part of the brain that is located below the thalamus, it is an area of the brain where several and very important homeostatic regulatory functions of the organism are integrated. Its main function is to link the autonomic nervous system with the endocrine system. Other functions are to control body temperature, control thirst and urine production (water balance in the body), control food intake, control uterine contractions and milk ejection in mammals, the coordination of the nervous system Autonomous, which affects smooth muscle and cardiac activity, influences behavior and expression of emotions. Therefore, the correct answer is B. Hypothalamus
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
