Answer:
D.
Explanation:
Loamy soil is made up of equal parts sand, clay and silt. These equal proportions provide the required growing solutions for plants, and make loam ideal for gardening.
Answer:
Explanation:
Both parents have black color and normal vision but some of their progenies show brown color and some shows PRA, this reveals the brown coat color and PRA are recessive traits and both parents are heterozygous. The progenies include black normal vision, brown normal vision and black, PRA, that is the alleles for these genes separate independently of each other.
Let us denote the alleles as B-black, b-brown and P-normal vision, p-PRA, then the genotype of the heterozygous parent is BbPp, alleles separate independently of each other so the possible gametes are alleles for the color and vision segregate independently during gamete formation.
Thus, option C is correct.
Answer:
The effect might be due to the gene expression.
Explanation:
The effect might be due to the variation in the gene expression in the organism. In this way, the variety of the genetic pool is likely to result in a diversity of the gene pool or genome. Because of the mutation and the environmental factors, there is likely to be a slight variation of the species. This results in a slight difference in the phenotypic expression.
Hey, it’s chlorophyll, it is stored inside the chloroplasts and gives them their green color! :)
