Question: What is the phenotype of XHY?

What is the phenotype for XhY?

Expression and Transmission

Phenotype Genotype
Normal female XHXH
Affected male XhY
Carrier female XhXH
Affected female XhXh

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.

What is the genotype of a man with hemophilia?

Since this is a recessive disorder, one XH allele will give a normal phenotype. 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.

Where is the genotype in a Punnett square?

To construct a Punnett square, the genotypes of both parents must be known. One parent’s alleles are listed across the top of the table, and the other parent’s alleles are listed down the left hand side. The resulting offspring genotypes are produced at the intersection of the parent’s alleles.

What is a phenotypic ratio?

A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another. When a researcher would like to obtain the gene expression for generations of an organism, they use the phenotypic ratio obtained from a test cross.

Is hemophilia homozygous or heterozygous?

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 heterozygous genotypes?

(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).

What are the 3 types of phenotypes?

With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.

Which description is an example of a phenotype?

Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

What is a genotype and phenotype?

The genotype–phenotype distinction is drawn in genetics. “Genotype” is an organism’s full hereditary information. “Phenotype” is an organism’s actual observed properties, such as morphology, development, or behavior. This distinction is fundamental in the study of inheritance of traits and their evolution.

Which macromolecule is involved in how hemophilia?

Factor VIII (FVIII) is a multi-domain glycoprotein that is an essential cofactor in the blood coagulation cascade. Its deficiency or dysfunction causes hemophilia A, a bleeding disorder.

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.
