plantlike organism on the planet Pandora can have three recessive genetic traits: bluish leaves, due to an allele (a) of gene A; a feathered stem, due to an allele (b) of gene B; and hollow roots due to an allele (c) of gene C. The three genes are linked and recombine. A geneticist performed a testcross with an organism that had been found to be heterozygous for the three recessive traits, and she was able to identify progeny of the following phenotypic distribution (+ = wild type):

 A) Genes are in the order: a-c-b

B) Genes are in the order: a-b-c.

C) Genes are in the order: b-a-c

D) Interference is one

E) Greatest distance between gene a and b

Choose the incorrect statement regarding the Van der Waals interactions & Hydrogen bonds

1. In Van der Waals interactions greater the area of contact the stronger the interaction.

2. In Van der Waals interactions greater the area of contact the weaker  the interaction.

3. Hydrogen bonds Relative strength is inversely proportional to the polarity More polar atoms form weak H bonds.

4. Hydrogen bonds Relative strength is directly proportional to the polarity More polar atoms form stronger H bonds.
