A plant breeder has determined the following variances for yield of corn in his fields:
Law Incorporation [45]

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

Suppose a group of bobcats that normally live and hunt in the tops of mountains, start hunting prey at the base of the mountain
posledela

Answer:

The correct answer would be b.  Their numbers will soon decrease.

Bobcats are opportunistic carnivores that feed on various types of prey such as mice, rabbits, voles, mountain beaver, gophers, yellow-bellied marmots, insects, birds, reptiles, and carrion.

If a group of Bobcats moves at the bottom of the mountain, then they will start hunting and eating all the prey available in the area.

It will result in the rapid decrease in the population of preys.
