#Question id: 15121

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

#Unit 5. Developmental Biology

Multiple factors regulate flowering in Arabidopsis. FT mRNA is expressed in companion cells of the leaf vein in response to multiple signals, including day length, light quality, and temperature. FT moves in the phloem from leaves to the apical meristem. FT is unloaded from the phloem in the meristem and interacts with FD.

FT-FD complex activates multiple genes. Which of the following combination is correct?(SS)
