The possible genotype would be when one of the parent is homozygous dominant - Phenotype ratio= 16:0, genotype ratio= 1 YYRR : 1YYRr: 1 yYRR: 1 YyRr.
when one of the parent is homozygous recessive the phenotype ratio is 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle and genotype ratio = YyRr: Yyrr: yyRr: yyrr or
1:1:1:1 genotype ratio.
Explanation:
The data given:
yellow and round dominant --- Y R
Green and wrinkle recessive ---- yr
It is given a true breeding plant, which means the parent plant is homozygous for the trait. Let one of the parent be YYRR
Also it is given that it was crossed with heterozygous parent so the other parent be YyRr
The cross between them is shown in punnet square as:
YR Yr yR yr
YR YYRR YYRr yYRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
YR YYRR YYRr YyRR YyRr
4 YYRR: 4 YYRr: 4 YyRR: 4 YyRr
thus genotype ratio is 1:1:1:1
phenotype ratio all 16 are yellow and round.
In case when either parent is homozygous recessive is crossed with heterozygous parent. The punnet square for this is shown as:
yyrr X YyRr
YR Yr yR yr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
yr YyRr Yyrr yyRr yyrr
4 YyRr: 4 Yyrr: 4yyRr: 4yyrr
1:1:1:1 genotype ratio
phenotype ratio = 4 yellow and round : 4 yellow and wrinkle : 4 green and round : 4 green and wrinkle.
Thus phenotype ratio is 1:1:1:1
The purple kernel is dominant over the yellow kernel and hence it has the genotype of homozygous dominant PP.
<h3>What is Genotype?</h3>
Genotype may be defined as the ultimate combination of alleles of genes that are selected for specific studies.
If it has some offspring with purple kernels and some with yellow, the genotypes of the two parents are heterozygous dominant for the purple kernel, i.e. Pp and Pp.
And when these two parents are crossed with each other, the genotypes are PP, Pp, Pp, and pp. While the genotypic ratio is 1:2:1 (PP: Pp: pp), but the phenotypic ratio is 3:1 (Purple: Yellow).
Therefore, it is well described above.

Answer:
The correct answer is - option D. A person rubs a shoe on a rug, causing extra electrons to be transferred to the shoe.
Explanation:
Current electricity is a flow of charged particles that moves through space or any type of electrical conductor. Usually, the transfer of the electric current takes place through a wire. There are many examples of current electricity such as lightning and static electric charge.
Electric static charge is generated due to the imbalance of particles present on the surface or within the material, normally friction leads to this imbalance in particles of the material such as when a person rubs his shes on rug created an imbalance in the electrons and then transfer to the shoe.
