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...)

When both dominant and recessive alleles are present within a single nucleus the organism is for the trait?
You are supposed to have 2 alleles in a single nucleus and if not there can be a disorder i believe.
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!
A single gene trait that has two alleles and that shows a simple dominant recessive pattern will result in?
A 3:1 phenotypic ratio (Mendelian inheritance).
Scientist have found fossils of the same organism on different continents what does this suggest?
Fosssils of the same organism found on different continents support the theory of continental drift. Continents that are now separated by large oceans were once part of a single large continent.
What are some single celled organisms?
Single celled is when an organism only has one cell, such as a paramecium. Single-celled is the same as unicellular. There is two kinds of cells: unicellular (single-celled) and multicellular ( has many cells).
Organism that has two diffrent alleles for a single trait?
An organism with two different alleles for a trait? is a hybrid
When a organism has two different alleles coding for a single trait it is?
Heterozygous
What do geneticists call alleles that are both expressed in the phenotype when they are together?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
What are both inherited alleles called?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
Which genotype shows an organism heterozygous for a single genes?
Aa
What are the dominate alleles?
Dominant allele disorders are single gene disorders which take effect in the heterozygous state.
If you are talking to a 14 year old kid and they ask you what heterozygous means what do you say?
well what you should tell the kid depends on what the kid already knows but if he/she will understand tell him/her that heterozygous is "Having two different alleles for a single trait."
Is A heterozygous pair of alleles is identical?
When there are heterozygous alleles for a gene thy code for a different expression of the gene. For example, the gene to taste PTC paper is a single gene trait. A person will have two copies (or alleles) for that gene (one from their mothers DNA, one from their father). There are two possible expressions for this gene - either you can taste the chemical or you cannot. When one allele is for tasting, and the other for not tasting, this is known as heterozygous. Both alleles are relating to the same gene but they giving different instructions and are thus not identical. When this happens, the dominant gene wins - in this case tasting is expressed. If the alleles are identical, they are known as homozygous and they are identical.
What is another name for heterozygous?
Another way to express something is heterozygous is to say it has dual alleles. There is a dominant and recessive allele. Alleles determine which traits something will have. Normally this is expressed in a single allele.
When both dominant and recessive alleles are present within a single nucleus the organism is for the trait?

What do you call an organism that possesses one dominant and one recessive genes for a single trait?
heterozygous
What do you call a organism that possesses one dominate and one recessive genes for a single trait?
heterozygous
