- In your own words, explain the meaning of the term heritability.Why is a heritability value valid only for a particular population ofindividuals raised in a particular environment?Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California. The females, which weigh around 1000 Ibs, are much smaller than the males, which may weigh up to 5000 Ibs. Suppose that scientists measured the weight of three adult female elephant seals and their female offspring. Parent Weight Offspring Weight 920 742 999 780 1014 787 Calculate the narrow sense heritability, h, of weight for female elephant seals to two decimal places. h?: What conclusions can be drawn from these data?Variance in back fat & body length were calculated in a heard of hogs and summarized in the table below. Trait In hogs Back fat Body length Vp 24.5 48.2 VG 15.5 28.4 VA 7.0 12.6 Calculate the narrow-sense heritability for body length, and provide an answer with 2 places behind the decimal. [h²] (Enter an answer with 2 or 3 significant figures)
- A correlation coeffiicient of zero means two variables do not vary in a consistent way with each other. True or false?You have been breeding roaches in your dorm and are trying to increase the speed in your roach population. 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. Round all answers properly to three decimal digits. Enter all answers without units so that they will be correctly recognized by Moodle. The numerical value for the standardized selection point is The numerical value for the truncation point is seconds. The numerical value for the selection intensity is Calculate the selection differential. S = seconds. The mean of the selected parents is seconds. The response to selection is seconds. The mean of the…What role would twin and adoption studies play in selecting a model for determining whether attendance at medical school is a heritable trait?

- Gray tree frog (Hyla versicolor) males call to females, and their calls can be characterized bythe pulse number and call period. The additive genetic variance of pulse number is 0.37,the additive genetic variance of call period is 0.16, and the covariance of the two traits is0.25. What is the additive genetic correlation of the two traits?Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California. The females, which weigh around 1000 lbs, are much smaller than the males, which may weigh up to 5000 Ibs.
