One way to assess whether a trait in males has a genetic basis is to determine how similar the measurements of that trait are among his offspring born to different' randomly chosen females. In a lab experiment. a group ofresearchers randomly sampled 4 male dung beetles and mated each of them to two different virgin females. The average body-condition score of offspring born to each of' the two females is listed for each male in the following table: Offspring bodyacondition score Male 1 2 1 1.0 1.2 2 0.? 0.3 3 1.0 0.? 4 0.6 0.9 A previous study found a repeatability of 0.80 using a similar experiment in a different species of dung beetle. Perform a statistical analysis. showing your calculations clearly outlining each step' in order to compare repeatability between these species (assume any assumptions are met). Compare the values providing a statistical explanation for the differences. as well as biological interpretation
