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 else can I help you with?
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
Compare homozygous alleles to heterozygous alleles?
Homozygous alleles refer to having two identical alleles for a particular gene (e.g., AA or aa), while heterozygous alleles refer to having two different alleles for a specific gene (e.g., Aa). Homozygous individuals will express the same trait, while heterozygous individuals may show a mix of the traits associated with each allele.
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = 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.
Differentiate between homozygous and heterozygous?
Homozygous refers to having two identical alleles of a particular gene, while heterozygous refers to having two different alleles of a particular gene. In homozygous individuals, both alleles are the same (e.g., AA or aa), while in heterozygous individuals, the alleles are different (e.g., Aa).
When two alleles of a pair are identical it is a condition if the two alleles are different this is a condition?
When two alleles of a pair are identical, it is referred to as homozygous. When the two alleles are different, it is referred to as heterozygous. Homozygous individuals have two identical alleles (e.g., AA or aa), while heterozygous individuals have two different alleles (e.g., Aa).
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?
2 different alelles - heterozygous Same alelles - homozygous
Having identical alleles?
Heterozygous
When the alleles of a gene pair are different they are said to be what?
They are considered to be heterozygous not heterosexual!
Compare homozygous alleles to heterozygous alleles?
Homozygous alleles refer to having two identical alleles for a particular gene (e.g., AA or aa), while heterozygous alleles refer to having two different alleles for a specific gene (e.g., Aa). Homozygous individuals will express the same trait, while heterozygous individuals may show a mix of the traits associated with each allele.
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.
What alleles of a gene pair are different?
heterozygous
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = 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.
The state of having two identical alleles for the same trait?
Heterozygous
What are two alleles that are different for a trait?
They are known as a heterozygous pair
Having non identical alleles are called?
Having non-identical alleles at a particular gene locus is known as being heterozygous. In a heterozygous individual, each allele is different, one inherited from each parent. This genetic diversity can lead to a variety of traits and characteristics in offspring.
