What else can I help you with?
The stronger of the two traits which show up in an organism is called a?
dominant trait. It is more likely to be expressed in the phenotype of an organism when it is inherited with a recessive trait.
How is the combination of genes important in determining the inheritance of biological traits?
The genes an organism contains is called the organism's genotype.
The principle or law of heridity which states that only the dominant trait can be seen in an organism that contains in genes a pair of contrasting traits is called?
This principle is known as the law of dominance or dominant-recessive inheritance. In this case, the dominant trait will be expressed, masking the recessive trait.
Using the terms dominant recessive explain the difference between genotype and phenotype?
No, I think you have your terms confused.The terms "dominant" and "recessive" are applied to alleles of a genotype. A genotype is an expression (using upper- and lower-case letters) that shows what alleles an organism has for a particular locus. The two alleles (in most cases) inherited (one from mother and one from father) can either be dominant or recessive. The recessive allele is not fully expressed in the presence of the dominant allele and is only expressed when there are two recessive alleles. The genotype could be called "recessive" I suppose if the genotype is homozygous recessive. But remember that two recessive alleles as a genotype is only one possibility - in which case you can't say the "genotype is recessive".The phenotype is dependent on the genotype. If present, the dominant alleles (in simple Mendelian genetics) will determine the phenotype - what the organism's trait or characteristic is. The phenotype will never be what is coded by the recessive allele unless the genotype is two recessive alleles.
What is the name given to the weaker trait that can be covered up by the dominant trai?
The recessive gene - less stronger than the dominant one.
The weaker of two genes is called what?
The weaker of two genes is called the recessive gene. In the presence of a dominant gene, the recessive gene is not expressed in the organism's phenotype.
What is an organism with one dominant and one recessive gene for a trait?
An organism with one dominant and one recessive gene for a trait is called a heterozygote. In this case, the dominant gene will be expressed in the organism's phenotype, while the recessive gene will not be expressed unless the organism inherits two copies of the recessive gene.
The stronger of the two traits which show up in an organism is called a?
dominant trait. It is more likely to be expressed in the phenotype of an organism when it is inherited with a recessive trait.
What is an observable trait of an organism that can mask a recessive trait?
The observable characteristic are called the genotype and any dominant trait can mask the recessive. An example would be Black Angus cattle can actually carry a red recessive trait because black is the dominant trait in cattle breeding
Trait of an organism that can be masked by the dominant by the dominant form of a trait?
A recessive trait is a characteristic of an organism that can be masked by the dominant form of a trait. It is only expressed when an individual inherits two copies of the recessive allele. Examples include blue eye color being masked by brown eye color.
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 gene is masked if it is paired with a dominant gene?
The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
What is a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
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.
What is allele masked by the dominant allele?
An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).
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 an allele that always shows up in an organism's phenotype called - an allele that masks the other allele?
An allele that always shows up in an organism's phenotype and masks the expression of another allele is called dominant. Dominant alleles are always expressed, even when paired with a recessive allele.
