#Question id: 9581

These four Photosystem II, Cytochrome b6 f, Photosystem I and ATP synthase integral membrane complexes are vectorially oriented in the thylakoid membrane to function as follows, find out the incorrect statements;

#Unit 6. System Physiology – Plant
  1. Photosystem II oxidizes water to O2 in the thylakoid lumen and in the process releases protons into the lumen
  2. Cytochrome b6 f receives electrons from PSI and delivers them to PSII It also transports additional protons into the lumen from the stroma
  3. Photosystem I reduces NADP+ to NADPH in the stroma by the action of ferredoxin (Fd) and the flavoprotein ferredoxin–NADP reductase (FNR)
  4. ATP synthase produces ATP as protons diffuse back through it from the lumen into the stromaprotein ferredoxin–NADP reductase

#Unit 8. Inheritance Biology

Plant height of wild Solanum nigrum is controlled by four pair of polygene. A plant genotype AaBBCcDd with 150 cm height but B plant genotype aabbccdd with 125 cm height present in their population. Following some plants with genotype AABBCCDD, AaBbCCDD, AabbccDD, aaBBccdd and their expected height in cm respectively is

A plant height in Maize is control by 3 pair of polygene. Two varieties of maize averaging 120 and 90 inches in height, respectively, are crossed. The F1 progeny is quite uniform averaging 105 inches in height. What will be height phenotype of F2 progenies ?

#Unit 8. Inheritance Biology

Numerous pure breeding crosses are made between two inbred plant strains, one having a mean height at maturity of 96 cm and the other as 56 cm. The height of the F1 progeny at maturity averages close to 76 cm. Height of plant control by four pair of polygene. The F2 progeny show the following phenotype.

Breeding experiment was performed on pure lines of tomatoes differing in fruit weight. The plants were all grown in a controlled environment chamber providing equal environmental conditions for all individuals as far as humanly possible. The results were as follows:

a) One dominants polygene contribution?

b) What will be frequency of 20 g in F2 CLASSES?

c) Number of polygene loci for this character.

#Unit 8. Inheritance Biology

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?
