Color blindness is an inherited trait that can be passed on through reproduction but it has some peculiarities. It is recessive and not very prevalent in the gene pool. Because of this, color blindness does not appear very often in the population. In addition, it is a sex-linked gene on the X chromosome. Thus males only have one gene to express color vision. If it happens to be the recessive allele, then males are color blind. Females, on the other hand, must have both alleles recessive in order to be color blind.

What else can I help you with?
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
Is albinism a dominant or recessive trait?
Albinism is a recessive trait.
When does a recessive trait dominant over a dominant trait?
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
Is diabetes dominant or recessive trait?
It is a recessive trait
In a hybrid individual the trait that is covered and not expressed is the what trait?
recessive
Is albinism a dominant or recessive trait?
Albinism is a recessive trait.
A living thing that shows a dominant trait may be homozygous dominant or homozygous recessive for the trait true or false?
False because a living thing that shows a dominant trait can not be homozygous recessive. If it is homozygous recessive it will show recessive trait. A living thing that shows dominant trait may be homozygous dominant or hetrozygous.
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
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.
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.
Not expressed when the dominant form of a trait is present?
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.
What a recessive trait?
A recessive trait is a trait that is not dominant, and is not really seen in ones phenotype.
Is glaucoma a dominant or recessive trait?
dominant
