There was only one saving grace for the Ultimate universe and the promise it had once held: Bendisâs Ultimate Spider-Man stories. Bendis was Marvelâs golden boy, and although his stories acknowledged that Ultimatum happened, Quesada never forced him to change the optimistic tone of his beloved series.
A heterozygote advantage (heterozygous advantage) describes the case in which the heterozygote genotype has a higher relative fitness than either the homozygote dominant or homozygote recessive genotype.
Often, the advantages and disadvantages conveyed are rather complicated, because more than one gene may influence a given trait or morph. Major genes almost always have multiple effects (pleiotropism), which can simultaneously convey separate advantageous traits and disadvantageous traits upon the same organism. common example is the case where the heterozygote conveys both advantages and disadvantages, while both homozygotes convey a disadvantage. A well-established case of heterozygote advantage is that of the gene involved in sickle cell anaemia.
