1. Phenotypes that decide the decide the development plan of the body do not vary in a population of organisms. Example, the segmentation of the body (number of hands, legs, ears, eyes, etc.).
2. Phenotypes that vary in a population are the eye color, hair color, hair growth, body size, body build, cold tolerance, skin color, etc.
3. Most of the phenotypes have a genetic basis, example, the colorblindness trait that is X linked inherited. But some phenotypes vary epigenetically, e.g., differences in body features of twins.
4. Yes, environment influences the phenotypes. Twins have a genetically identical DNA yet they have minute differences in their skin color, eye color, body build, etc. Such differences arise when the environment differently affects the gene regulation within the body of the twins.
Well, since the phenotype is checkered, we assume that there is codominance where offspring phenotype is a mix of the parents' phenotypes. If the offspring phenotype is a blend between the two parents', then there is incomplete dominance.
Genotypes of codominant parents is usually represented by upper case letters B and W, and the mixed genotype would be BW.
Since the genotype BW is 100%, the rooster's genotype can only be BB and the hen's genotype can only be WW to result in 100% BW.
The correspond Punnett square is therefore
B B
W BW BW
W BW BW
By the way, apparently that this example is academically made up, there are no checkered chickens. I don't know if this is true, since I don't raise enough chickens to verify this. :)
One asks the question that is there a good time to start a war whereas the other says that winter is the bad time to start the war.
<h3>Conversation in the picture</h3>
In this cartoon, two persons are talking to each other on the rise of tension between Ukraine and Russia. They are arguing about the time of the war which is started by Russia.
Nowadays there are tension between Ukraine and Russia which puts pressure on the oil market as well as leads to large destruction in Ukraine. One asks the question that is there a good time to start a war whereas the other says that winter is the bad time to start the war.

Answer: A cell containing half the number of chromosomes of a somatic cell and able to unite with one from the opposite sex to form a new individual; a gamete. Good luck!
