For example, small ears, long arms, and brown eyes are all phenotypes.

What keeps Chinese people looking Chinese?
Inasmuch as the appearance (phenotypical manifestation) of Chineseness is genetically determined, the fact that such an appearance is not deleterious in terms of reproductive fitness means that there is no selection pressure tending to remove the genotypical determinants of the phenotypical appearance of Chineseness.
What is the process for genetically changing goats?
You can't change them into something they're not. If you want to change an individual's offspring characteristicstha's called selective breeding. Genotypical and/or phenotypical.
When geneticists refer to the physical characteristic of an organism they are talking about its?
It's phenotype. ( also includes behavioral characteristics )
Does convergent evolution result in speciation?
All evolution that results in increasing genetic divergence between subpopulations may result in speciation. That includes convergent evolution: convergence occurs at the phenotypical level, not at the genetic level.
Can several alleles affect a single trait?
When there are multiple alleles present for a trait a variety of phenotypical outcomes is possible. These traits can be dominant, recessive, co-dominant, or incompletely dominant.
Natural selection can only act on traits?
Yes, traits that are phenotypical in nature and confer some survival and reproductive advantage, then the alleles that gave rise to these traits become more frequent in the populations gene pool and evolution takes place. So, natural selection is acting on genes in the individuals and population are evolving from this process.
Perform the following cross rrgg x RrGg What is the phenotypic ratio?
All you need to do is use a Punnet Square for this. You will get the following genotypical and phenotyical ratio from this cross: RrBb x RRbb = RRBb RrBb RRbb Rrbb In terms of phenotypical ratios, 50% of the offspring have a chance of showing R and B, and the other half have the chance of showing R and b.
Why do you need to look at genetics at both organismal and the molecular level?
If you look at how Mendel studied his pea plant seeds, he saw that RRand Rr genotypes of seeds produced round seeds and rr produced wrinkled. This is from a phenotypical (or you can say organismal) level. However, when scientists cracked open these seeds, it was found that the Rr genotypes had only 50% of a protein, but it still looked round. RR had 100% of the protein, and rr had 0% of the protein. This is a case of Incomplete Dominance, but Mendel didn't realize it because he had no microscope to look inside the seed.So it's important to look at both the organismal and molecular level of genes.
If you think you are adopted and know who may be your real mother how would you go about verifying that information?
Well, if possible, snatch some hair, saliva, or something and have a DNA test run. However, I think that requires the consent of the person in question, so . . . If that doesn't work out, then compare phenotypical features: Potential Mother has brown hair . . . You have brown hair . . . Check! Potential Mother has one eye . . . You have one eye . . . Check! Potential Mother has a cleft chin . . . You have a cleft chin . . . Check! I'd say by then you're getting pretty close. Nevertheless, you could just be being paranoid.
