Skin Pigmentation in humans
Explanation: Polygenic inheritance- It is simply a single characteristic which is controlled by more than two genes. Human skin's color is determined by the amount of dark pigment it has which is melanin
. Minimum four genes are involved in the melanin production.
It is a case of continuous variation as the combination of melanin producing allele are responsible for degree of pigmentation
Answer: freeze-thaw cycles and hot and cold cycles
Explanation:
This phenomenon is not rare in the animal kingdom. Known as alternative mating strategies, it is employed by a subgroup of males that are usually incapable of facing the larger males in direct confrontations.
These "sneaky males" as they are sometimes called, will employ alternative strategies to mate with females. Which strategy will be dominant is dependent on the environmental factors and is not permanent. In some conditions where food is not that abundant, there will be less larger males and thus, the smaller males employing this strategy will be more common. At other times the opposite will occur.
However, in most cases and most probably here, the end result will be a coexistence of this traditional and alternative mating strategy, where males will exhibit a greater diversity in phenotype.
Answer:
Energy is the ability to do work. The main chemical compound cells use for energy is adenosine triphosphate (ATP). Ribose is a 5-carbon sugar molecule that is part of an ATP molecule.
