Plant Breeding and Predicting Offspring Traits
By Patty Hain - croptechnology.unl.edu
Introduction
Kernel color in an easily observable trait. There are different alleles of the ‘kernel color’ gene that code for different colored kernels. For example, one allele represented with Y (upper-case) encodes yellow colored kernels. Another allele for the color trait encodes white colored kernels represented with the y (lower-case).
Answer: Segmented Worms
Explanation: Annelid worms have a interesting, segmented type of body.
(Sorry if this is incorrect, have a good day though!)
Answer:
Option-B
Explanation:
Phototropism refers to the movement of plants in response to light. The mechanism of phototropism involves the photoreceptors which respond to a different wavelength of light: the phytochromes to red light, cryptochromes to blue light and the phototropin to the UV light.
Plants integrate the signals obtained from these receptors and then activates the gene which will be involved in the phototropism.
The gene could be the production of the auxin hormone and the PIN proteins which helps in the distribution of the auxin in the plants. Due to the production of this hormone and its distribution in the shoot, the grass tips bend towards the light.
Thus, Option-A is correct.
Answer: The Central Nervous System and The Peripheral Nervous System
