Haemophilia is a x linked recessive trait. A gene 'h' is responsible to cause haemophilia in human.A woman who is haemophilic(very rare) will have "h" gene in his both chromosome i.e. XhXh. A male has not been a carrier for haemophili either he is normal or haemophilic. The genotype of a normal male is XHY0.
Hence in Y chromosome there is no haemophilic gene so we take it as Y0.
A normal X chromosome will be taken as XH
Draw a Punnett square for a cross between a woman who has hemophilia (X-linked recessive inheritance)...
SEX-LINKED TRAITS 8. Create a Punnett square to determine the offspring that would result from a cross between a woman with normal vision, who carries the allele for color-blindness, and a man who has normal vision. Note: color-blindness is an X-linked recessive tret What are the genotypes of the parent? List all possible genotypes of the offspring. male, normal male, color-blind female, normal vision female, carrier 50% Co hat percentage of their sons would be color-blind? What percentage of their...
A certain type of hemophilia is X-linked recessive in humans. A woman has this disease and has children with a man who has normal blood clotting (no hemophilia). All their [ Select ] ["sons", "daughters", "children (regardless of their sex)"] will have hemophilia.
6. Hemophilia is a sex-linked trait. A person with hemophilia is lacking certain proteins that are necessary for normal blood clotting. Hemophilia is caused by a recessive allele so use "XH” for normal and "Xh" for hemophilia. Since hemophilia is sex-linked, remember a woman will have two alleles (XX) but a man will have only one allele (XY). A woman who is heterozygous (a carrier) for hemophilia marries a normal man: a. What are the genotypes of the parents? b....
Hemophilia in humans is a recessive sex-linked trait. A man with hemophilia and a woman who does not have hemophilia have a daughter who does not have hemophilia. She then marries a man who does not have hemophilia. What is the probability that their first child will be a daughter with hemophilia? A daughter without hemophilia? A son with hemophilia? A son without hemophilia? If the couple has four sons, what is the probability that all four will be born...
A woman with the recessive, X-linked disorder hemophilia has children with a male who is color-blind, also a recessive X-linked disorder. What is the probability that their children will have hemophilia and have normal vision? a. 0 b. 1/4 c. 1/2 d. 3/4 e. 1
1. Hemophilia is a sex-linked recessive disorder. If a male hemophiliac has children with a woman who is homozygous normal (has no family history of the hemophilia trait), what percentage of his male children would be hemophiliac (so, ignore the females) (a) 50% (1/2) (b) 100% (2/2) (c) 0% (0/2) 2. To perform a test cross, you cross an organism with a a. homozygous dominant b. homozygous recessive c. heterozygote
Hemophilia is a sex-linked X-linked recessive trait. A homozygous normal woman marries a normal man whose brother has hemophilia. What are the chances of them having a hemophiliac son; hemophiliac daughter?
In humans, hemophilia is a sex linked trait. Females can be normal, carriers, or have the disease. Males will either have the disease or not (but they won’t ever be carriers) X H X H = female, normal / X H Y = male, normal X H X h = female, carrier X h X h = female, hemophiliac / X h Y= male, hemophiliac Show the cross of a man who has hemophilia with a woman who is a carrier....
NAME: 6. Red-green color deficiency is an X-linked recessive trait. A woman with normal color vision has a father who is color-deficient. The woman has a child with a man with normal color vision. Which phenotype is NOT expected as a possibility for that child? a) a color-deficient male b) a color deficient female c) a male with normal color vision d) a female with normal color vision 7. Which of the individuals in the human pedigree shown below allow...
36. In X-linked recessive inheritance, which of the following is not true? A. They appear much more frequently in males vs. females. B. Genes for sexed linked disorders are usually carried on the X chromosome. C. Females are typically carriers of disease, but do not show an affected phenotype. D. Affected males can pass the gene to their daughters, but they (daughter) are usually unaffected. E. All of the above are true.
