So woagyina ahwehwɛ anim na wode kanea ketewaa bi asɔ w’ani pɛn? Sɛ woyɛ saa a, wubehu sɛ kurukuruwa tuntum ketewaa a ɛwɔ w’ani mfinimfini a wɔfrɛ no pupil no twetwe bere a hann no hyerɛn no.

Sɛ yɛbɛka no tiawa a, dɛn ne Marcus Gunn Pupil (RAPD)?
Okay, momma yɛmfa eyi nhyɛ ɔkwan a ɛyɛ mmerɛw so. Fa w’ani sɛ adwumayɛfo baanu a wɔbom yɛ adwuma. Hann yɛ sɛnkyerɛnne a efi wo ti (i.e., w’amemene) mu ba. Sɛ aniwa biako nya saa sɛnkyerɛnne yi a, ɛsɛ sɛ aniwa abien no nyinaa bom yɛ adwuma na ɛbubu aniwa tuntum abien no nyinaa.
Nanso sɛ hann bɔ obi a ɔwɔ Marcus Gunn Pupil aniwa a ayɛ no yaw no a, saa aniwa no nnye nkrasɛm no yiye na ɛde nkɔ amemene no mu. Ne saa nti, nkuruwankuruwa tuntum a ɛwɔ aniwa abien no nyinaa mu no ntew yiye. Ɛtɔ mmere bi a, sɛ́ anka wɔbɛtew so no, ebia ɛbɛyɛ te sɛ nea wɔreyɛ kɛse kakra.

Dɛn nti na eyi rekɔ so? Dɛn ne nea enti a ɛte saa?
Marcus Gunn Pupil no fi wo retina anaa w’aniwa ntini a ɛde nkrasɛm fi aniwa no mu kɔ amemene no mu no sɛe titiriw. Momma yɛnhwɛ aduruyɛ mu tebea atitiriw a ebetumi aka eyi.

Wobɛyɛ dɛn ahu eyi, Oduruyɛfo?
Eyi yɛ biribi a wuntumi nnya wɔ fie. Sɔhwɛ titiriw bi wɔ hɔ a oduruyɛfo yɛ ma eyi. Wɔfrɛ no "Swinging flashlight sɔhwɛ." Wɔsan frɛ no Marcus Gunn sɔhwɛ.
Wɔyɛ eyi saa:
