Which of the following examples would NOT be consistent with a gene dosage effect?

#Unit 8. Inheritance Biology
  1. Males with one normal allele for the X linked gene dystrophin are unaffected, while females (who shut off one of their two X chromosomes) with one normal allele for dystrophin may be mildly affected with muscular dystrophy.
  2. Flower colour in four-o-clocks seems to be incompletely dominant.
  3. In fruit flies, homozygotes for an allele that produces a small amount of functional protein are severely abnormal but survive to adulthood, while homozygotes for an allele that produces no protein at all die as embryos.
  4. In bels Males normal are haploid while females normally are diploid

Stomata from intact, attached leaves of Arabidopsis illuminated with blue, red, and green light in a growth chamber, increases and decreases their aperture in response to light.

 

Find the CORRECT statements from the above graph.

i) Stomatal aperture increases when the green light is turned off, and close when the green light is turned on again

ii) Stomata from the phototropin-less double mutant phot1/phot2 respond to blue light and open further when green light is turned off

iii) stomata from the zeaxanthin less mutant npq1 do not respond to blue light and least effect to opening of the stomata further when green light is turned off

iv) the npq1 mutant and phot1/phot2 double mutant response indicate that the green reversal of the blue-light response requires zeaxanthin but also phototropin

The “core autophagy machinery” controls the initiation and growth of the autophagosome and has been divided into three main protein groups:

i. A-ATG9, B-TOR, C-PI(3) Complex

ii. A- ATG9, B-PI(3) Complex, C-TOR

iii. The TOR kinase complex acts as a negative regulator of autophagy

iv. The TOR kinase complex acts as a positive regulator of autophagy
