Even though around 10% of cri-du-chat patients may have gotten the deletion from a parent (if the parent has something called a balanced translocation, which does not cause problems and would not otherwise be diagnosed), it is usually a randomly occurring deletion of part of a gene. That means that it happens without a family tendency or condition, and occurs very early in fetal development. A gene which is recessive or dominant is a "whole" gene that is either expressed or not expressed in the offspring. Though it may seem like a random occurrence when you have a child with blue eyes, or red hair, those traits can be traced back through the family. Not so with a condition like cri-du-chat. It is one of those unfortunate random events that occur in nature, and can be very severe or not too severe, depending on how much genetic material is lost.

What is it when an allele is neither dominant nor recessive?
this is called codominance when alleles are neither dominant or recessive.
Is Lyme disease dominant trait or recessive trait?
Neither. It is a disease passed on by the deer tick. "Dominant" and "Recessive" have nothing to do with it.
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
Is a gender a dominant or recessive gean?
Purebreds can be recessive or dominant, depending on their genotype. A genotype for spots on a griaffe could be AA (purebred dominant), Aa (heterozygous dominant), or AA (purebred recessive)? AA and Aa would both show the dominant phenotype, but only AA and AA are purebreds.
What is codominance?
It's like incomplete dominance, but instead of one allele not being completely dominant for a trait, both alleles for that specific trait are dominant.A condition in which neither of two alleles of a gene is dominant nor recessive
What is it when an allele is neither dominant nor recessive?
this is called codominance when alleles are neither dominant or recessive.
If the alleles are neither dominant or recessive what happens?
If neither are Dominant Or Recessive then its called co dominance or spuedo - dominance
What trait is neither dominant or recessive?
Codominant.
Alleles are neither dominant nor recessive?
codominance
Is Lyme disease dominant trait or recessive trait?
Neither. It is a disease passed on by the deer tick. "Dominant" and "Recessive" have nothing to do with it.
Is the mutation asthma recessive or dominant?
Asthma doesn't have a gene so its neither
When neither gene in a genotype pair is dominant and neither gene is recessive the genes are said to be .?
Incomplete dominant alleles.
Is turners recessive or dominant?
It is neither recessive nor dominant because it is a chromosomal disorder and not just a problem present in a single gene.
How is it possible to have neither allele dominant?
You have two recessive alleles
Why some chromosomes are recessive and the others are domainent?
Actually a chromosome consists of many genes/alleles and is neither recessive or dominant in and of itself.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
Is Down syndrome a dominant or recessive?
Down syndrome is neither dominant nor recessive. Actually, it is considered to be an "autosomal" trait. This occurs when there is damage to the chromosome.
