What is it called when neither trait is dominant?

What is it called when neither trait is dominant?

Codominance. Incomplete dominance occurs in the heterozygote, in which the dominant allele does not dominate the recessive allele entirely; rather, an intermediate trait appears in the offspring. Codominance occurs when the alleles do not show any dominant and recessive allele relationship.

Can a trait be neither dominant or recessive?

Not all genes are either dominant or recessive. Sometimes, each allele in the gene pair carries equal weight and will show up as a combined physical characteristic. For example, with blood groups, the A allele is as ‘strong’ as the B allele. The A and B alleles are said to be co-dominant.

When neither allele for a trait is dominant?

Incomplete Dominance In this case, neither allele is dominant. Cases in which one allele is not completely dominant over another are called incomplete dominance. In incomplete dominance, the heterozygous phenotype lies somewhere between the two homozygous phenotypes.

Can a trait be dominant?

Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene. A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present.

What is co dominance explain with an example?

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.

What makes a trait dominant or recessive?

Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

What makes a trait dominant?

Why is the dominant trait not always the most common?

Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive.

Can a trait be dominant if both parents have it?

Both parents had the recessive gene. If only your parent has a trait would that be a dominant or recessive? if one of your parent has the trait and you do not that means the trait is recessive and the dominant trait lies with the other parent. If both parents have the trait and you do not, this means that you might wanna get a DNA tst lol.

How are recessive traits and dominant traits expressed?

Dominant trait is a genetics term. A dominant trait is one which will be expressed if one of the parents has the gene for that trait. A recessive trait is one that will be expressed only if both parents carry the trait. How is it possible that two unattached earlobe parents have a child with attached earlobes?

Can you have two copies of a recessive trait?

Yes, if both parents have one copy of a recessive trait, you could end up with two copies and express that trait even if neither of your parents did. How might it be possible to show a trait when both parents do not show it? you just do want you got to do How might it be possible to show a trait when both parents don’t show it?

Can a trait be hidden from your parents?

Yes, because a trait can be hidden for one generation and return in the next. For example, if a girl had red hair, but neither of her parents had red hair, she could have inherited from her grandparents. Therefore, it can be inherited from someone other than your parents.
