What is the relationship between dominant and recessive alleles in a heterozygous organisms?
it means there is one of each. in a homozygous gene it means that there are two of the same. for example if "t" repressents a recessive trait and "T" represents a dominant trait, then an organism with a gene that is tT would be considered heterozygous, and a gene that is TT or tt would be considered homozygous or "pure bred"

What is the relationship between dominant and recessive allelse?
Dominant alleles are those that express their traits even when only one copy is present, while recessive alleles require two copies to manifest their traits. In a heterozygous individual (one dominant and one recessive allele), the dominant allele will mask the effect of the recessive allele. This relationship is fundamental in genetics, influencing inheritance patterns and phenotypic traits in organisms.
What is organisms with 1 dominant and 1 recessive gene?
An organism with one dominant and one recessive gene for a particular trait is said to be heterozygous for that trait. The dominant gene will typically mask the expression of the recessive gene, resulting in the dominant phenotype being expressed. For example, if "A" represents a dominant allele and "a" represents a recessive allele, the heterozygous genotype "Aa" will display the trait associated with "A."
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What term describes an individual that has a dominant and a recessive allele for a trait?
The term for an individual with a dominant and a recessive allele for a trait is "heterozygous." This means they have two different alleles for a specific gene, with one being dominant and the other recessive.
Are organisms with alleles BB recessive or dominant?
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.
What is it Dominant allele What is a recessive allele?
A genotype in which there are both a dominant and a recessive allele is called heterozygous.
What is the opposite of homozygous of dominant?
heterozygous recessive
What is the differences between homozygous dominant and homozygous recessive and heterozygous?
Homozygous dominant individuals have two copies of the dominant allele for a trait, homozygous recessive individuals have two copies of the recessive allele, and heterozygous individuals have one copy of each allele. Homozygous dominant and heterozygous individuals will express the dominant trait, while homozygous recessive individuals will express the recessive trait.
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.
What does does heterozygous mean?
Heterozygous means that you are carrying 1 dominant trait and 1 recessive trait.If an allelic pair has one dominant and other recessive gene it is called heterozygous.
Is heterozygeous dominant or reccesive?
Heterozygous means that it carries both dominant and recessive traits (as opposed to homozygous which carries only one) - the dominant trait is the one which is expressed (phenotype). A heterozygous trait can be expressed as Rr - "R" the dominant trait and "r" the recessive trait.
What term describes an individual that has a dominant and a recessive allele for a trait?
The term for an individual with a dominant and a recessive allele for a trait is "heterozygous." This means they have two different alleles for a specific gene, with one being dominant and the other recessive.
What is the probability of 2 heterozygous individuals producing a heterozygous recessive offspring?
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
An example of a heterozygous recessive genotype is?
An example of a heterozygous recessive genotype is when an individual carries one dominant allele and one recessive allele for a particular trait. One example could be a person with the genotype Aa, where "A" represents the dominant allele and "a" represents the recessive allele.
