Information demonstrate below are SNP genotypes of Guinea hogs from Kizzi Roberts’ research project. In each cell “1” codes for one homozygote (TT for example), “-1” for the other homozygote (AA for example), and “0” for a heterozygote (AT for example). A “u” means that the genotyping reaction failed and the data are missing.
a. Calculate the proportion polymorphic and average heterozygosity for the population.
b. The Identify the four pigs you would keep for breeding if you had the objective of maximizing genetic variation in the next generation and describe the criteria that you used for making selection decisions.
