Question

2. A farmer is selectively breeding koala sheep to increase wool production. The farmer starts with a population that annually produces 6.8 kg of wool per sheep (standard deviation = 2.2 kg). He chooses the top 10% of wool produces to breed the next generation; these koala sheep have a mean annual production of 11.3 kg of wool per koala sheep (standard deviation- 1.4 kg). The next generation has a mean annual production of 10.4 kg of wool per koala sheep (standard deviation = 2.0 kg). GenerationMean Wool Production (kg/yr) Standard deviation (kg/yr) 2.2 1.4 2.0 6.8 ії.3 10.4 Second Generation Based on this information, what was the selection differential in this population of koala sheep? (2 pts) Was the response to selection in this population of koala sheep? (2 pts)

Answer 1

Solution is in image format.I wrongly put 3 in place of 2 as question no. Kindly avoid that and focus in solution.

Meanwhile give a like if it helps you.

3. ANS: 3a. ANS: Selection differential (SD) is a difference between measures of superiority of the selected parent koala sheep used for breeding to increase wool production over the total of the population of sheep. SD 11.3 6.8 4.5 kg/yr 3b. AN sheep refers to difference between the wool production in parent generation and the next offspring generation. S: Selection response(R) in the population of Koala R 10.4 - 6.8 -3.6 kg/yr
