Answer:

100% black

Explanation:

<em>The allele for black is dominant over that of the grey fur.</em>

Let B represents the allele for black color and b for grey color.

Homozozygous black rabbit will have the genotype: BB

Heterozygous black rabbit will have the genotype: Bb

If the two are crossed;

BB   x   Bb

Offspring: BB, Bb, BB, and Bb = 2BB and 2Bb

2BB = Black fur

2Bb = Black fur (heterozygous)

Both BB and Bb offspring are black phenotypically.

<em>Hence, all the offspring will appear black, a phenotypical ratio of </em><em>100% black.</em>

The enhancement of contrast at the edge of an object is the result of: lateral inhibition in the retina. the color of the object
ZanzabumX [31]

Answer:

lateral inhibition in the retina

Explanation:

Horizontal cells are in contact with photoreceptor cells through the synapse. One photoreceptor forms an excitatory synapse with horizontal cell in the adjacent regions of the retina while the horizontal cell forms an inhibitory synapse with another photoreceptor.  

Hence, as one photoreceptor activates the horizontal cell, the horizontal cell, in turn, inhibits the other photoreceptor cell and thereby reduces the quantity of neurotransmitter released at the bipolar cell. In this way, horizontal cells transmit lateral inhibitory stimulus to the photoreceptor which in turn improves the contrast at the edges of the object.
