Which genotype shows a woman who has hemophilia?

What is the genotype of a female with hemophilia?

Females having one normal and one abnormal gene are asymptomatic carriers and will transmit the abnormal gene, on average, to one half of their sons and one half of their daughters.

Expression and Transmission.

Phenotype Genotype
Carrier female XhXH
Affected female XhXh

What genotype causes hemophilia?

Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern . The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes . In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition.

What genotype is XHXh?

A female x A male hemophiliac

The female had the genotype XHXH, and produced the two normal gametes seen at the left side of the diagram.

What is the genotype of a female with hemophilia quizlet?

The female is XhX The male is XY There is a 25% chance that the offspring would have hemophilia (XhY). The other possible outcomes would be XhX, XX, XY. In humans, hemophilia is inherited as a sex-linked recessive trait on the X chromosome.

Is hemophilia A genotype or phenotype?

Haemophilia was previously regarded as a classical example of Mendelian inheritance, with mutation in only a single gene (F8 or F9) causing the disease phenotype. The disease manifests complete penetrance. Studies, however, revealed the striking genetic and phenotypic heterogeneities of the disease.

Is hemophilia heterozygous or homozygous?

The disease is inherited as an X-linked recessive trait and thus occurs in males and very rarely in homozygous females. Heterozygous females for the disease are known as carriers.

What are the genotypes of all the individuals with hemophilia?

The genotypes of the males in a pedigree for sex-linked inheritance are easy to determine since normal blood clotting (N) is dominant and hemophilia is recessive (n). Since these alleles are on the X chromosome only, a male represented by a clear square will have the genotype XNY. A darkened square will be X”Y.

What genotype does not have hemophilia?

When the offspring do not have a XH and only have the Xh allele/alleles they will have the hemophilia condition. Man’s genotype is XhY. Daughter’s genotype is XHXh (She got the Xh from her father. She has a normal phenotype, so we know her other allele is XH.

XB Xb
Y XBY XbY

Does XY mean female?

Sex chromosomes usually determine whether you are female or male. Women are XX. Men are XY.

What are the 3 types of genotypes?

There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
