The electronic transitions of the peptide bond occur in the far UV. The intense peak at 190 nm, and the weaker one at 210–220 nm is due to the p!p* and n!p* transitions.

X-Linked Color Blindness in Humans 

The human eye perceives color through light-sensing cone cells that line the retina.  Each cone cell contains one of three pigments capable of absorbing light of a particular wavelength: one absorbs blue light, a second absorbs red light, and a third absorbs green light.

Y-Linked Characteristics

Y-linked traits—also called holandric traits—exhibit a distinct pattern of inheritance.  These traits are present only in males, because only males possess a Y chromosome, and are always inherited from the father.
