What is an example of complete dominance in flower color?
In Figure 1, for example, neither flower color (red or white) is fully dominant. Thus, when homozygous red flowers (A1A1) are crossed with homozygous white (A2A2), a variety of pink-shaded phenotypes result.
What is a complete dominant?
Complete dominance is a form of dominance in the heterozygous condition wherein the allele that is regarded as dominant completely masks the effect of the allele that is recessive. For instance, for an individual carrying two alleles that are both dominant (e.g. AA), the trait that they represent will be expressed.
What is an example of incomplete and complete dominance?
Chickens with blue feathers are an example of incomplete dominance. When a black and a white chicken reproduce and neither allele is completely dominant, the result is a blue-feathered bird.
What are some completely dominant traits?
Examples of Dominant Traits
- Dark hair is dominant over blonde or red hair.
- Curly hair is dominant over straight hair.
- Baldness is a dominant trait.
- Having a widow’s peak (a V-shaped hairline) is dominant over having a straight hairline.
- Freckles, cleft chin and dimples are all examples of a dominant trait.
Is wavy hair incomplete dominance?
Wavy hair is an example of incomplete dominance. An individual with curly hair (CC) and an individual with straight hair (cc) mate, all of their offspring have wavy hair.
Which of the following is an example of co dominance?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
Are dimples complete dominance?
Dimples are usually considered a dominant genetic trait, which means that one copy of the altered gene in each cell is sufficient to cause dimples.
Which is an example of codominance apex?
In both codominance and incomplete dominance, both alleles for a trait are dominant. In codominance a heterozygous individual expresses both simultaneously without any blending. An example of codominance is the roan cow which has both red hairs and white hairs.
What is dominance with example?
dominance, in genetics, greater influence by one of a pair of genes (alleles) that affect the same inherited character. If an individual pea plant with the alleles T and t (T = tallness, t = shortness) is the same height as a TT individual, the T allele (and the trait of tallness) is said to be completely dominant.
Can two parents with curly hair have a child with straight hair?
It is not possible for two ‘unmixed’ parents having straight-hair to reproduce an offspring with curly hair. If both parents have curly hair, it is more likely to inherit that trait of curly hair.
