What is used to describe when a genotype is either both recessive or dominant?
The term used to describe when a genotype consists of either two dominant alleles or two recessive alleles is "homozygous." When an organism has two identical alleles for a trait, it is homozygous dominant (for two dominant alleles) or homozygous recessive (for two recessive alleles). In contrast, if the alleles are different, the organism is referred to as "heterozygous."
What type of alleles are present in an organism?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
If an organism has alleles Bb it is?
If an organism has alleles Bb, it is considered heterozygous for that particular gene. This means it has two different alleles for that trait, one dominant (B) and one recessive (b). The dominant allele usually determines the organism's phenotype, while the recessive allele's effects may only be expressed if the organism is homozygous (bb).
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
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.
Which of Mendels laws states that an organism with two different alleles will express the one that is dominant?
Law of Dominance
What type of alleles are present in an organism?
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
Organisms that has two different alleles for a trait?
An organism with two different alleles for a trait is said to be heterozygous for that trait. This means that it has one dominant allele and one recessive allele. The dominant allele will usually determine the organism's phenotype for that trait.
How are dominant alleles often represnted?
Because they are dominant alleles, they normally show on the physical form of the living organism.
What is two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
What is the difference between a herezygous and a homozygous?
"Heterozygous" and "homozygous" are terms that refer to alleles, which, in genetics determine what trait, from which parent, will appear in the offspring. Alleles can be either Dominant or Recessive. Every organism has two alleles, which can both be dominant, both recessive, or one of each.So,If an organism heterozygous, it has one recessive and one dominant allele.If an organism is homozygous then both of its alleles are the same; you need to specify if they are homozygous recessive (both alleles are recessive) or homozygous dominant (both alleles are dominant).
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.
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.
If an organism has alleles BB?
The organism is homozygous dominant for that trait.
What happens if an organism has two factors for a domintnat trait?
If an organism has two factors (alleles) for a dominant trait, the dominant allele will be expressed in the phenotype. This is because dominant traits mask the effect of recessive alleles, so the presence of two dominant alleles will result in the dominant trait being displayed.
What is the condition in which there's more than one dominant allele?
Codominance is when an organism has two different dominant alleles, so both of them are expressed.When an organism has two identical dominant alleles, it is homozygous.
What is Co-dominant Alleles?
Co-dominant alleles are two different versions of a gene that are both fully expressed in a heterozygous individual. This means that both alleles contribute to the phenotype of the organism. An example of co-dominant alleles in humans is the ABO blood group system, where A and B alleles are co-dominant to each other.
