... an individual is homozygous recessive for that allele or the locus is autosomal (or sex-linked) recessive. It can also happen if there is a mutation or loss of the other copy and the only available copy for the locus is the recessive copy.
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
recessive
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
Recessive traits are not expressed when the dominant form is present. This is because the dominant allele masks the expression of the recessive allele in the heterozygous condition. Only when an individual has two copies of the recessive allele will the recessive trait be expressed.
A recessive trait is one that will only be expressed when in the presence of two recessive alleles.
It is a dominant trait. You only need one gene of a dominant trait for that trait to be expressed. You need two copies of the recessive trait in order for the trait to be expressed.
recessive
A dominant trait is expressed when an individual has one or two copies of the dominant allele, while a recessive trait is only expressed when an individual has two copies of the recessive allele. Dominant traits mask the expression of recessive traits in heterozygous individuals.
Recessive traits. This means that the trait is only expressed when an individual inherits two copies of the recessive allele for that trait, one from each parent.
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.
A recessive trait is a trait that is not shown or expressed physically but is retained within the persons genes, whereas a dominant trait is a trait which opresses the recessive trait and is prodominantly shown or expressed physically. For example it is possible for two red-haired parents, both with recessive dark haired genes, to have a dark haired child. they must both have the recessive gene or the dominant gene of red - hair will be expressed in the child
Recessive traits are not expressed when the dominant form is present. This is because the dominant allele masks the expression of the recessive allele in the heterozygous condition. Only when an individual has two copies of the recessive allele will the recessive trait be expressed.
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
Both of the alleles must be recessive. The trait expressed is a recessive trait.
You wouldn't see a recessive trait if an individual has one dominant and one recessive allele for that trait. In this case, the dominant allele's phenotype will be expressed, masking the recessive trait. The recessive trait would only be visible if an individual has two copies of the recessive allele.
