Barley alongside Emmer wheat was among the first domesticated crops Although today it is mostly about two thirds of annual production grown as foddor and as fermentable material in beer brewing there s a great interest in it as source as of useful genes for improvement of wheat and other cereals You cross two highly inbred barley strains that differ in resistance to drought and then self cross the F1 progeny to raise the F2 generation In which generation s will you find the highest genetic variation In the F2 In the F1 In the parental generation and F1 In the parental generation In the F1 and F2 Question 7 4 5 pts In your attempt to identify those drought resistant varieties of barley you are collecting seeds from wild varieties of barley you collect in the central Jordan Valley and grow them in your greenhouse at ASU s polytechnic campus While you indeed observe that most of the newly collected plants are highly drought tolerant the broad sense heritability is close to 0 This means that much of the observed phenotype variance in the population is due to heritable traits little of the observed phenotype variance is due to genetic differences little of the observed phenotype variance is due to environmental factors
