In fruit flies, the gene for red eyes (r) is dominant and the gene for sepia eyes (r) is recessive. if a red-eyed heterozygous fly (rr) mates with a sepia-eyed homozygous fly (rr), what are the possible genotypes of their offspring? (hint: you many want to complete a punnett square.) rr only rr, rr, and rr rr and rr rr and rr

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
