Colorblindness is a sex-linked recessive trait. if b=normal and b=colorblind, what would be the genotype of a normal male? question 1 options: xby xbyb xbxb xby

XBY

Explanation:

Males have X and Y chromosomes, so we ca eliminate the third option.

Because he is normal and not a carrier, we can eliminate the second option.

Because he is also not colorblind, we can eliminate the first option.

That leaves us with XBY

Hope this helps

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
