## Question

###### 4Adog breeder has asked you for advice: She would like to breed Alaskan huskies that run faster for sled dog racing events The table below shows the running speeds (m/s) of 15 familles of dogs ! in the breeder'$ kennel:Note: Midparent values average trait values of fatherand mother; Midoffspring values average trait values of the ofispring:Running speed of Family Midparent (m[s)_ 113 45 13.8 12.6 29 8.8Running speed of Midoffspring (mIs) 10.9145 12.3 6,593145 9.6 29 13.6 11.4 12.5 48 14.953

Their mean ngspereds were: 14.9 m/s,145m/s,13,8 m/s, 13,6 m/s,and 12.5 m/s Assuming the Roand unning speed ofthe population is 10.71 m/s Calculate the selection differentiai (S) Round numbers to 2 decimal places: (2 pts)
