Tay-Sachs is an autosomal (not sex linked) recessive disorder which has no effects at birth but leads to blindness, paralysis, mental retardation and death by three to four years of age.
i have tay sachs and i am dead HAHA WORL SUK IT
Klinefelter's syndrome is neither a dominant or recessive trait. It is caused because X chromosome in the mother's egg does not divide properly, so instead of one X from the mother fusing with one Y from the father, you get two Xs fusing with one Y. Also, men with Klinefelter's syndrome cannot pass it to their children, because they are almost invariably sterile.
Beta thalassaemia follows predominantly recessive inheritance, however there are some dominant mutations. People with only one copy of the recessive mutation are carriers, they have a few small problems but are otherwise healthy and comfortable.
cystic fibrosis is a recessive gene because both parents have to have the gene and pass it on so that there child can get it. this is why a child has a one in 4 chance of getting the disease if both parents carry the gene because they have to get the cystic fibrosis gene from both parents.
Obesity can be considered a dominant disorder-R.S.J
It is a dominant trait.
recesive i think but im ot sure
It's neither. It's a disease.

if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
if u have a recessive gene with a recessive gene then u can see the recessive gene but if you have a dominant gene with a recessive gene you can only see the dominant gene hope that helps:)
dogs have a dominant and a recessive copy of a gene
Most genes have two copies of each gene with dominant gene "trumping" the recessive one. The gene is recessive because it is said not to do much of anything unless paired with another recessive gene, but if paired with a dominant gene, the dominant gene wins.
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
Most cases of triple X syndrome are not inherited so it is not a dominant or recessive trait.
It takes 8 copies of a recessive gene to overpeower dominant gene
The dominant gene will always "cover up" the recessive gene, although there are instances of codominance, in which both phenotypes will be displayed, because one gene is not completely dominant over the other. There is also what is called 'incomplete dominance', when the actual phenotype is somewhere between the two.
Dominant trait is the one which is expressed when the homologous pair of genes controlling it are either homozygous or Hetrozygous dominant; on the other hand recessive trait has both genes to be homozygous recessive. in fact trait is controlled by the form of genes. Dominant gene expresses even when it is in the company of recessive gene. However recessive gene expresses only when in company of recessive gene
The gene that expresses itself over the other is Dominant. The former gene is recessive.
Recessive gene is one which is supressed and do not show their characteristics and dominant gene is one which show their characteristics for example if a father has brown hair and mother has black hairs and if their son has black hair then in this case gene which has characteristics of black is dominant and the other which has characteristics of brown colour is recessive
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
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.
