Suppose a farmer is interested in developing a breeding program on his chicken farm. The farmer would like to artificially select for egg weight, egg shape, shell color, and shell thickness. In a large population of his chickens, the farmer has measured these four continuous egg traits of interest and calculated their variances, shown in the table below.

Variance Weight Shape Shell Color Shell Thickness
Phenotypic 166 1043 157 176
Additice Genetic 4 140 83 22
Environmental 83 522 95.4 220
Dominance Genetic 5 657 19.8

8

Which trait would best respond to artificial selection by the farmer?

A) Shell Color

B) Egg Shape

C) Egg Weight

D) Shell Thickness

Select that statements that identify how the farmer might utilize the information gained from his data.

A) Identify quantitative trait loci correlated to each trait examined in the chicken population after obtaining genetic sequence data for his chicken population.

B) Recommend a selective breeding program for a population of chickens from another country based on his results.

C) Design an experiment to improve the shell thickness trait in the current chicken population by changing the farm environment.

D) Further inbreed the chickens on the farm with the largest egg shell thickness to improve the overall phenotype.

A farmer focusing on the production of eco-friendly chicken eggs collects the following data about his output. In a sample of 50 eggs, the farmer finds the average egg to weigh 47 grams. The standard deviation of the egg weight is 2 grams and the distribution of weights resembles a normal distribution reasonably closely. The farmer can sell the eggs to a local distributor. However, they have to be in the interval between 44 grams and 50 grams (i.e., the...
