Correct answer: B). Coarse, infertile soil is usually found near the base of a mountain.
The course, infertile soil is normally found near the base of the mountains. It provides stable bases for the high mountain. It helps to keep the ground firm and it would take a longer time to erode and evolve. These soil are a type of loamy soil. The nature of erosion can affect the composition and structure of these type of soil. Rest all other options are false.
Hence, the correct answer would be option B
b. polygenic traits
c. codominance
d. incomplete dominance
The right answer is A. multiple alleles.
The multiallelic genes contribute to the study of polymorphism and genetic variability of individuals as well as populations.
In multi-allelic genes, individuals are differentiated by several alleles that exist in several forms.
For example: in a certain region of the genome there may be a single nucleotide polymorphism (SNP), one can find either an adenine or a guanine (bi-allelic).
A genetic factor exhibiting a trait even in the presence of alternative forms is described as a dominant allele. Dominant alleles express over recessive genes, as exhibited in the height trait of pea plants.
A genetic factor for a trait that is always expressed when present is referred to as a dominant allele. In genetic terms, alleles are variations of a gene. In a pair of alleles, one can be dominant and the other recessive. When an individual possesses both the dominant and the recessive allele, the trait associated with the dominant allele gets expressed. For example, for the gene concerning height in pea plants, the allele for tallness is dominant over the allele for shortness. Thus, when a plant inherits the tall and short alleles together, the tall trait is expressed due to the dominance of the tall allele.
