What happens to the actual image you see between the time you see it and it your brain registers it?
USPshnik [31]

Answer AND Explanation:

As light reflected from an external object enters the eye, it is refracted by the cornea, aqueous humour, the lens and vitreous humour so that an image is focused on the retina. The image is real, upside down and smaller than the object. The photoreceptor cells are stimulated by the reflected light and impulses are set off. The impulses are transmitted by neurons through the optic nerve to the optic region of the brain. The brain interprets the impulse as an upright impression of the object.

In corn, smooth kernels (K) are dominant to wrinkled kernels (k).
Roman55 [17]

Heterozygous means 2 different zygotes. Since Smooth kernels are dominant, Zygotes KK and Kk will be smooth and kk will be wrinkled.

If you were to set up a Punnett Square chart like:

           K     k

   K   (KK)    (Kk)

   k   (Kk)     (kk)

the ratio for smooth to winkle would be  3 : 1

Which Will be 75% Smooth  and 25% Wrinkle
