Heterozygosity implies possessing both a dominant and a recessive allele and the phenotype that is exhibited in a heterozygote is always the dominant one (hence the name 'dominant'). Therefore, if a phenotype is associated with heterozygosity, it is automatically the dominant phenotype.

Yes when paired with a homozygous gene it can. Every gene has two allele's associated with it. If we took the following example of two parents with and their offspring:

HH (parent 1 dominant copy of the gene)

hh (parent 2 recessive copy of the gene)

Their offspring would HAVE to be Hh

HH x hh = all offspring carrying 1 big H and 1 small h

It is NOT possible for someone to expressive a recessive gene and be heterozygous. Dominant genes always "dominate" in those situations so if someone has blue eyes for instance, you know they have the recessive gene combination for that.

Heterozygous means when an organism has both a dominant and recessive allele for a certain trait. Because it has both a recessive and a dominant, it would be dominant.

What is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?

That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.


An organism with two different alleles for a single trait is said to be heterozygous?

A heterozygous is a hybrid of genes. It has a dominant and recessive gene. The dominant gene covers over the recessive trait, making the individual have the dominant trait. (trait are alleles...) or apex ans:two


If two genes in a gene pair are for the same trait what will that trait be?

The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.


A trait that is hidden?

The trait that is hidden is recessive trait.


What does a heterozygous organism have?

It depends on the context. The only way to demonstrate practically that an organism is homozygous for a particular trait is to cross it (breed it) with another showing the recessive phenotype for that trait. When enough ofspring have been produced to be statistally significant then the conclusion can be drawn. It may also be possible to deduce whether an organism is homozygous by knowing the genotypes of the parents. Also, if you already know which phenotype is dominant then an organism showing the recessive phenotype is, by definition, homozygous. Of course, this all only applies to single gene inheritance!

What is an organism with one dominant and one recessive gene for a trait?

that organism is a heterozygous one which contain the traits of recessive as well as dominant genes.


What are traits that are hidden called?

Recessive traits can be hidden if the organism inherits one dominant and one recessive allele (i.e. is heterozygous) for a gene. If a heterozygous organism mates with another heterozygous organism for the same trait, the recessive trait may be expressed in their offspring, which would mean that the offspring inherited two recessive alleles, one from each parent.
