A population of farmed salmon average 9 pounds in weight at two years old. To
select for rapid weight gain, fish with an average two-year weight of 12 pounds are
selected for breeding. If the narrow-sense heritability (h²) for two-year weight in the
unselected population is 0.2, what will be the average two-year weight of the
offspring of the selected fish?
9.2 pounds
9.6 pounds
10.8 pounds
12.2 pounds
12.3 pounds
If I'm given this information and I am told that the average estimated heritability was determined to be 0.13 and 0.28 for weaning weight and hip height. How do I use the information in the table to determine statistically whether weaning weight and stature have improved?
You estimate the heritability of milk production in the brown cows at your friend’s farm. The heritability is H2=0.45. Identify the following that best describes the conclusions you can make from your study.
a.
Cows that produce milk at lower rates than at your friend’s farm occurs because they have bad genes.
b.
Cow milk production in this population is dependent on both environmental and genetic influence.
c.
Milk production is not heritable in your friend’s population of cows.
d.
Milk production heritability at the farm 15 miles down the road is also likely to be 0.45.

You measure speed by timing how quickly the roaches race along the linear track in your dorm room. Your current population mean is 9.3 seconds with a standard deviation of 0.32 sec. You selected the fastest 10% of your current population to be parents of the next generation. The broad and narrow sense heritability values for racing speed in roaches are 0.93 and 0.78, respectively. You wish to develop a faster population of roaches.
