It’s important to know the possible genotypic and phenotypic ratios of different genetic crosses because the the phenotype shows what the offspring will physically look like what the genotype is what genes the offspring carries. phenotype doesn’t always show what alleles the offspring carries because if the offspring is heterozygous for the gene only the dominant allele shows and the recessive allele won’t be visible. the genotype can see what alleles the offspring carries, both dominant and recessive. knowing the genotype helps to know what alleles are passed on. if one of the parents have a genetic mutation that is passed on, the phenotype helps see what ration of offsprings will have the mutation visible and the genotype will help see what ratio of offsprings will pass on the allele for the mutation
probably isn’t useful. my brain is currently burnt
Alleles can disappear from a population through natural selection. This relates to the most fit phenotype because the breed with the desirable trait, or the most fit, will live and produce off spring. Eventually the less desirable trait and its corresponding allele will disappear after multiple generations pass. If the environment does not change alleles of non desirable traits will disappear. <span />
With skepticism and open-mindedness, they both revolve around the fact that they don't "confine" themselves in an idea.
However, the difference comes with the means of not confining themselves. With skepticism, you are questioning that idea and essentially, taking that idea with a pinch of salt. With open-mindness, however, you aren't questioning the idea but rather are willing to open yourself to other ideas aside from that singular idea.
Here's an example (it's simplified, but you should understand the difference):
Skepticism: I used to believe in idea A, however after scrutinizing it I'm starting to doubt idea A.
Open-mindness: I believe in idea A, however I want to understand ideas B and C as well.
