hemophilia is a recessive gene, if you are A female that is a carrier then if you were to have a male child it will be passed on to him. As well as if you were to have a male child who would have hemophilia. your daughter would need to be tested to see if she carried it as well. Only Males have hemophilia but females carry it.
My family has dealt with hemophilia for years.
My great Aunt carrier, her son has hemophilia
My mother a carrier, my brother has hemophilia, I do not carry it.
My Aunt is a carrier, my cousin he has it, his sister carrier as well.
The scientific answer is
This is due to the fact that females have two X chromosomes while males have only one, lacking a 'back up' copy for the defective gene the defective gene becomes manifest more easily in males. Because females have two X chromosomes and because haemophilia is rare, the chance of a female having two defective copies of the gene is very low, thus females are almost exclusively asymptomatic carriers of the disorder.
recessive
Recessive
dominant-appears in first generation recessive-seems to dissapear
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
bcoz in case of one dominant and one recessive, dominant allele will express its characters and suppresses the recessive ones. so for the expression of recessive characters both allele should be recessive.
Alleles can be dominant or recessive
is malignant melanoma dominant or recessive
Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
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.
Recessive
recessive
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.
is restless leg syndrome dominant or recessive
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
it is dominant
recessive.
It is recessive
