John, noted acarologist (he studies mites) and fancy humming bird breeder hobbyist, is attempting to breed giant puffing humming bird that he can present at the fancy balls given in his glittering social circle. After years of experimenting with humming bird, John has found that the slope of the least squares regression of Midoffspring on Midparent values is 0.75. All the humming birds were allowed to breed, and a first batch of offspring was produced. The table below presents data on the puffing ability (in cm3) of 10 breeding families of humming bird in his dovecote: Family midparent mid offspring (first batch) 1 55 56 2 68 72 3 77 81 4 37 40 5 25 30 6 34 32 7 44 44 8 23 49 9 60 39 10 67 68 John was disappointed in the puffiness of the first batch of offspring, so he shipped all these offspring to market. John desperately wanted to breed an even bigger, puffier humming bird, so for a second batch of offspring, he let only certain humming bird breed. Noting that families 1, 2, and 3 have midparent values that are above average, he allowed only the parents in those three families to breed. Baron , noted ornithologist, thought that he could do better. All his life he has dreamed of wiping John eye and delivering a total, public, and embarrassing humiliation. So the Baron hatched a plan to steal mating pairs from three different families in John dovecote and breed them in order to make an even bigger and puffier humming bird. In addition, the Baron stole the document that showed the least squares regression of Midoffspring on Midparent values, so he knows that the slope of this line is 0.75. a) Which parents should he steal? Why? b)For these purloined pigeons, what would the selection differential be? c) Calculate a response to selection, as above. d)What is the predicted average puffing ability of the humming bird in the next generation? (Calculate in the same manner as above) e) Who bred the bigger, puffier humming bird? f)John, suffering from his stinging defeat in the humming bird breeding contest, hired the noted German geneticist, Von , to analyze his humming birds . Von has determined that John dovecote has such excellent climate control that environmental variance is effectively zero. If the phenotypic variance (VP)of this trait is 0.5, what must the additive genetic variance (VA) be? Please answer all questions they are all limked
