A 32-year-old man complains of frequent urination. He is overweight (280 lb, 5 ft 10 in tall), and after measuring the 24-hr creatinine clearance, you estimate his GFR to be 150 ml/min. His plasma glucose is 300 mg/dL. Assuming that his renal transport maximum for glucose is normal, as shown in the figure above, what would be this patient’s approximate rate of urinary glucose excretion?

Two varieties of maize averaging AABBCC (200 inch) and aabbcc (80 inch) in height, respectively, are crossed. The F1 progeny is quite uniform averaging 140 inches in height allowed to self fertilization. If height is control by 3 pair of polygene, what is the height of following genotype of F2 plant?

I- AaBBCC     II- aaBbCC       III- aabbCc

Two varieties of maize averaging 25 and 125 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 75 inches in height. Of the 500 F2 plants, the Shortest 2 is 25 inches and the tallest 2 are 125 inches. What will be number phenotype observe in F2 progeny and number of polygene contribute for that character respectively?

Plant height is control by polygenetic trait. Plant having height 6 cm are allowed to cross with plant having height 2 cm , all F1 progeny having height uniform 4 cm were allowed selfing to produced F2 progeny in which 5 out of 320 with height of 6 cm. What will be phenotype ratio in F2 generation?
