We have to find the force of gravity of an object that has a mass of 20 kg and then to choose the correct answer. The formula for the force of gravity is: F = m * g, where m is the mass of an object and g is the acceleration of the gravity ( on Earth : g = 9.81 m/s^2 ). F = 20 kg * 9.81 m/s^2 = 196.2 N, or approximately 196 N. Answer: A. 196 N<span>.</span>

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.
