Incomplete dominance is when a cross between two true breeds (homozygous) having different genotypes and phenotypes result in an heterozygous offspring expressing a third trait, usually a blend of those of the parents.
An example is crossing between red and white roses resulting in pink roses.
The condition to conclude incomplete dominance is that the heterozygous individual expresses a trait which is different from, and is a blend of, the traits of the parents.
Scientists most often produce new genetic variations of organisms by causing mutations with radiation or chemicals and then selectively breeding in order to emphasize the desired traits in the new variations. The Dachshund is an example of this. By breeding two dogs with a similar mutation that caused student legs and elongated backs breeders were able to create a new variation not found in nature.

Explanation:
En física, la materia es todo aquello que se extiende en cierta región del espacio-tiempo, que posee energía y está sujeto a cambios en el tiempo y a interacciones con aparatos de medida. Se considera que es lo que forma la parte sensible de los objetos perceptibles o detectables por medios físicos.
Etimológicamente, proviene del latín materia, que significa «sustancia de la que están hechas las cosas» y que también alude a la «madera dura del interior de un árbol»;1 la palabra está relacionada con māter («origen, fuente, madre»)2 y se corresponde con el griego hyle3 (de hylos: «bosque, madera, leña, material»)45 que es un concepto aristotélico de la teoría filosófica del hilemorfismo.6
El uso moderno del término va más allá de la noción clásica de sustancia, y los físicos denominan materia a cualquier entidad cuya presencia en una cierta región del espacio-tiempo conlleva que el tensor energía-impulso para dicha región es diferente de cero.
The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.

Answer:
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust.
