Question

Imagine that a Wolf breeder has asked you for advice. The breeder keeps Red Wolves, which she races in illegal wolf racing events. She would like to breed wolves that run faster. The table below gives data on the running speeds (m/s) of fifteen families of wolves in the breeder's kennel. I prepared a scatterplot of mid-offspring values versus mid-parent values from the data below. Approximately what is the narrow sense heritability of running speed in the breeder's wolf population? O NOS Y = 0 4631x+5495 R20 2452 Mid-parent value O 5.495 O 0.4631 O 0 2452 lo 1.0

there isnt any

Answer 1

The equation mentioned in the graph, y = 0.4631x + 5.495 is in the form of y = mx + c. So here m = 0.4631

In case of regression line graph drawing relation between mid value of parents and offsprings, the slope of the regression line represents the narrow-sense heritability (h2).

Thus the narrow sense heritability of running speed in breeder's wolf population is 0.4631

Thus option B is correct.
