  2. What does dominant generation mean - Biology Stack Exchange

    biology.stackexchange.com/questions/14187

    Therefore, I'd say that, the dominant generation is the generation which have the longest mean generation time (=mean time from the birth to reproduction). As @Shigeta said in the comments: For example, in Homo sapiens, the dominant generation is the diploid phase (sporophyte, you and me) and the non-dominant generation is the haploid phase ...

  3. On wageningenur.nl (random website I never heard of before), they define dominant and codominant markers based on gene expression suggesting that the terms dominant and codominant used for markers have the same definition than those used for allelic effects on the phenotype (dominance, recessivity, overdominance, etc..). Questions

  4. Dominant genes are often variant genes which convey a new ability (phenotype) and as such the trait can show up with just one copy has this variant. Phenylthiocarbamide tasting is an example of this dominance. If both copies of the gene were the variant, the original ability might disappear - making the original trait dominant as well.

  5. What does it mean for a protein to be dominant-negative?

    biology.stackexchange.com/questions/96112/what-does-it-mean-for-a-protein-to...

    I am not sure what exactly is meant by a protein being dominant-negative. I have searched online and found that dominant negative refers to a mutation whose gene product adversely affects the normal wild-type gene product within the same cell (with this occurring if the product can still interact with the same elements as the wild-type product ...

  6. How is incomplete dominance explained at the molecular level?

    biology.stackexchange.com/questions/88534

    Protein formed from recessive allele can show dominance over the dominant allele, and this is known as Dominant negative. The protein produced from one allele is faulty and prevents other allele's protein to work properly. Both the proteins interact with each other in particular cell. Genetic trait for red hair is an example of dominant negative.

  7. Dominance coefficient - Biology Stack Exchange

    biology.stackexchange.com/questions/59132/dominance-coefficient

    As it was pointed out in the comments, this is the definition of dominance. Though, I thought that dominance of one allele means only which phenotype will prevail in the heterozygote case and I cannot find the relation between the two definitions .

  8. molecular biology - Is RFLP markers are dominant or codominant...

    biology.stackexchange.com/questions/53045/is-rflp-markers-are-dominant-or-co...

    On the other hand, if a heterozygous (m/+) offspring has a mutant phenotype then we would say that the mutation is dominant over the wild-type allele. Your question is asking about a test cross of a +/+ individual to a homozygous mutant ( m/m ), however, in this case the RFLP does not typically have any mutant phenotype, it is just a convenient ...

  9. What is the definition of a mutation? - Biology Stack Exchange

    biology.stackexchange.com/questions/43159

    The term mutation can be used with two different meanings. Each definition can further be split into two different more detailed definitions. The reason for this slight mess is mainly historical. In short, a mutation can refer to. An event narrow sense; broad sense; An allele definition based on ancestral/derived states; definition based on ...

  10. Comparison of examples in incomplete dominance and Co dominance

    biology.stackexchange.com/questions/63913

    The definition they give is. inheritance in which the paternal influence is dominant in one group of cells and the maternal in another. It is a little vague to me as 1) the phrasing is a little unusual and 2) it does not specify the underlying mechanism. If anything, it feels like a synonym of codominance and not of incomplete dominance.

  11. How is incomplete dominance different from codominance?

    biology.stackexchange.com/questions/24364/how-is-incomplete-dominance...

    incomplete dominance is when one allele is partially dominant over the other allele of the same trait.both these alleles are dominant but one is more powerful than the other .for examples a mating between a white female and black male in humans and have a colored child. co-dominance is when two alleles are equally expressed.
