How Does Natural Selection Create Ordered Variation?

... one. And if factors change most of the time they don't change for all individuals of a species - only for a population. So you get a variety of phenotypes. And if species can't adapt to occuring changes they will eventually die out, but that may take a few couple of hundreds of thousands of ...

Re: Theories - Origin of Life

... mechanisms correct those errors (or cause the resulting piece of DNA to be so broken that it isn't viable) so that by the time you are looking at phenotypes, most mutations are neutral because many of the most harmful ones have been weeded out.

Re: I Need Help understanding gametes, genotypes and phenotypes

I do not know how to go about this question. A man who has type AB blood marries a women with type B blood (her genotype is I^Bi). What phenotypes and genotypes of children could they produce. Would I do a punnet square with AB and Ii?

I Need Help understanding gametes, genotypes and phenotypes

I am having trouble understanding how to figure out the ratio of genotypes and phenotypes. The question says: There is an allele E which codes for unattached earlobes in humans. The allele e codes for the attached earlobes which do not hang free. If a ee male marries ...
