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.
Homozygous and Heterozygous. If an organism has two copies of the same allele, for example AA or aa, it is homozygous for that trait. If the organism has one copy of two different alleles, for example Aa, it is heterozygous.Keep in mind that an organism can't simply be 'homozygous,' period.or example, the allele that gives rise to albinism is recessive, and the allele for normal pigment production is dominant. That means that a heterozygous individual with the genotype Aa, who has one copy of the normal allele and one copy of the albinism allele, would not be an albino.
