yes.
dominant trait
recessive
For a dominant trait to be expressed, you either need a RR or an Rr genotype. The other genotype, rr, is recessive only. In genetics, capital letters represent a dominant allele, and lower case letters represent the recessive allele.
The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait. For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink coloured petals). This is because P is dominant to p, and will always be expressed. Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.
There are many types of dwarfism. Acondroplastic dwarfism is a dominant trait. Living individuals are heterozygous for the trait as a homozygous dominant individuals have substantial skeletal anomalies that result in death in infancy.
Dominance in genetics means the trait that will express more readily than a recessive trait. A dominant trait can express if only one parent has it.
In genetics, the phenotype represents the physical characteristic/trait. For example brown eyes is a phenotype. When referring to alleles which are alternative forms of a gene, it is the dominant allele that is represented physically. For example if brown eyes are a dominant trait, then they would be represented physically in the genotypes BB and Bb.
If a trait is dominant, then an organisms heterozygous (hybrid) for that trait would normally show: A) The recessive trait only B) The dominant trait only C) A blend of the recessive and dominant traits D) A phenotype unlike that of either parent B) The dominant trait only! Reason being because heterozygous means the pair of genes are different. When this occurs, only the dominant trait is expressed.
it is because that trait is more dominant. when a dominant and a recessive trait combine it is most likely that hte dominant trait will be expressed. it is only when a recessive trait combines with an another recassive trait that hte trait gets expressed(which is rare and not so commonly occuring)
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.

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.
