In the diploid ancestor of our modern bread wheat (Triticum aestivum), resistance to a particular fungal pathogen is controlled by a dominant allele at a single locus. Assume that a population of this diploid wheat is in Hardy-Weinberg equilibrium and that the frequency of the dominant (resistance) allele is \( 0.67 \). In each of the following parts, we suggest carrying your answer to three decimal places. a. What proportion (decimal value) of the population is phenotypically resistant to the pathogen? Tries \( 0 / 3 \) b. Assume that all susceptible individuals in this population are eventually killed by fungal infections before they reproduce. What is the frequency of the recessive (susceptibility) allele among the survivors? (HINT: count the alleles) Tries \( 0 / 3 \) c. Assume that the surviving plants cross-pollinate randomly and that each plant produces the same number of seeds. What proportion of the seeds produced will eventually become plants that are susceptible to the fungus? Tries \( 0 / 3 \)
