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!

∙ 12y agoHomozygous means "alike genes". For example, consider this.
Your father has brown hair, he has the gene for brown hair and blonde hair.
Your mum has blonde hair, she has two genes for blonde hair.
Your father is heterozygous, your mum is homozygous.

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
What genotype could be described as heterozygous?
Yes - Hh is heterozygous. HH is homozygous, and hh is homozygous.
What are the symptoms of heterozygous?
There are not symptoms of heterozygous since it is not a disease or condition that you can get. It is a genetics term that refers to whether a gene is dominant or non dominate.
What is an example of two heterozygous parents?
The possible genotypes of parents who are heterozygous would be found using a punnet square. The outcome would be 50 percent heterozygous dominant, 25 percent homozygous dominant, and 25 percent homozygous recessive.
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 is an organism with 2 alleles for 1 trait that are different?
The answer to your question, "What is an organism with 2 of the same alleles for a trait called?" is homozygous. it is just homozygous-By SciienceFreak
Scientists call an organism that has two different alleles for a trait is what?
an organism that has two different alleles for a trait is heterozygous
Organism that has two diffrent alleles for a single trait?
An organism with two different alleles for a trait? is a hybrid
Describes an organism that has two different alleles for a trait?
Heterozygous
An organism with two different alleles?
The organism is in heterozygous condition.
It an organism has two alleles that are different then the individual is?
heterozygous for that specific gene.
This is the name of an organism with two different alleles?
The organism is heterozygous for that allele.
What word describes an organism that has the genotype Bb?
The most accurate description of an organism with genotype AaBb is heterozygous. A homozygous genotype is aaBB and AA.
What organism with two unlike genes of a trait is called?
A heterozygous has 2 different alleles for a trait.
Organism possessing two identical genes for a trait is said to be?
An organism that has two different alleles of the same gene is a heterozygous organism. Due to the various effects of different alleles, an organism's traits do not reveal its genetic composition.
An organism that has two different for a trait is heterozygous?
alleles
