mr_godi [17]

Character displacement differs from resource partitioning because character displacement  is directly linked to the evolution of genotypes that have allowed alternate resource use

<h3>What is genotypes ?</h3>

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. The number of copies of each chromosome found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene.

In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two alleles for each gene. Homozygous refers to a genotype when both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.

Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.

Tom [10]
Let's think of it like this.  We have an energy crisis, but how can we solve it?  There are three steps.  First, we need to recognize that we HAVE a problem that needs to be fixed.  Then, we need to determine what's causing the problem.  Finally, we need to change how we act in order to solve the problem.  Now, let's look at the options.

Is A correct, leaving our behavior unchanged?  NO: if we know the cause of the problem, we still need to solve it!  What about B: the problems are ignored?  NO: you can't solve a problem unless you know it's a problem.  C?  NO: to solve a problem, you need to find out what's causing it.  Finally, let's look at D: behavior is changed after cause is identified.  This is correct: not only do we know why it's happening, but we're fixing it!
