L-Cysteine has traditionally been obtained by extracting it from acid hydrolysates of human hair and animal feathers. High levels cannot be synthesized from glucose because l-cysteine feedback inhibits the enzyme, which catalyzes one of the steps in the biosynthesis of l-cysteine. These enzyme are,

#Unit 8. Inheritance Biology

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
