Answer:
Explanation:the optic nerve is a cable -like grouping of nerve fibers it connect and transmits visual information from the eye to the brain. In human eye it receives light signal from about 125million photoreceptor cells referred to as rods and cones through 2 intermediate neuron types , bipolar and amacrine cells.
After crossing over of peonies, one with purple flowers and long stems, and the other with white flowers and short stems we will get the number of offspring 83 with purple flowers and short stems; 29 with purple flowers and long stems; 26 with white flowers and short stems; and 9 with white flowers and long stems.
A dominant allele is one that nullifies the effects of a recessive allele. The allele that is covered up by the dominant allele is known as a recessive allele.
This shows that a plant with purple flowers and long stems is carrying a dominant allele that masks the effect of the recessive allele in a plant with white flowers and short stems.
