Some people have hitchhiker's thumbs, which bend backwards with a large angle between the two segments (phalanges). The myth is that there are just two kinds of thumbs, straight thumbs (S) and hitchhiker's thumbs (H), and the trait is controlled by a single gene with two alleles, with the allele for S being dominant.This was proposed by Glass and Kistler (1953) and has been the subject of very little research since then.he myth is that there are just two kinds of thumbs, straight thumbs (S) and hitchhiker's thumbs (H), and the trait is controlled by a single gene with two alleles, with the allele for S being dominant.

Two fundamental cellular processes are cellular respiration and photosyn-thesis. Cellular respiration is the process by which cells release stored energy from sugars. Photosynthesis is the process in which producer cells use carbon dioxide, water, and nutrients to produce glucose and oxygen.
They require cells to use water Which of these is true for both photosynthesis and cellular respiration Both occur in all organisms. Both occur in most producers. Both produce carbon dioxide. Both... show more They are simple chemical reactions. They are complex chemical reactions. They require light energy from the sun. They require cells to use water. Which of these is true for both photosynthesis and cellular respiration. Both occur in all organisms. Both occur in most producers. Both produce carbon dioxide. Both produce oxygen. Which of these organisms could be chosen for a study of both photosynthesis and cellular respiration.
