Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition. What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?) 0% 1/4 or 25% 2/4 or 50% 3/4 or 75% 4/4 or 100%

Hemophilia A, a condition in which blood does not clot properly, is a recessive trait located on the X chromosome (Xh). A woman heterozygous for the trait marries a normal male. What is the probability that this couple will have hemophiliac daughters? What is the probability that this couple will have hemophiliac sons?
Hemophilia is a sex-linked recessive trait. A male hemophiliac and phenotypically normal female have a son with hemophilia. They would like to have one more child. What is the probability of having a child without hemophilia? Explain using a Punnett square. Is it possible for a girl to be born with hemophilia? Explain.
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a phenotypically normal man with no family history of hemophilia. What is the probability that their first son will have hemophilia? 1/4 1 3/4 0 1/2
Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? (use the letter “H”)
A woman who is a carrier for X-linked hemophilia (she does not have the disease) marries a man who does not have hemophilia. They have a daughter, named Angela, who does not have the disease. Angela marries George, who also does not have hemophilia. Angela and George have a son named Robbie. What is the chance that Robbie will have hemophilia? O 1/4 O 1/3 O 1/2 0 1/8
Hemophilia is a blood disorder which is sex-linked. A woman carrier has children with a normal man. Determine the chances for girls and boys with hemophilia. [Remember that females have the XX genotype and males have the XY genotype. Do not place an allele on the Y chromosome. Example: XN Xn for female; Xn Y for male]
I will be adding two questions here because I asked two of the same questions twice by accident earlier. A man and a woman do not have hemophilioa, but the womans father did. (Hemophilia is X-linked recessive). a) What is the probability that they will have a child with hemophilia? b) Is it possible for any of their daughters to be affected? Explain. A cross between a horse homozygous for red hair and a horse homozygous for white hair results in offspring with the coat colour called roan. When you look at the fur of the roan offspring you see both red and white hairs. What type of inheritance best explains this? a) blending inheritance b)codominance c)incomplete codominance d)multiple alleles
Normal No Spac Hemophilia is a blood clotting disorder that almost exclusively affects males. It is a sex-linked, recessive disorder (X). Using the details below, fill in the Punnett square to determine the percent probability of the couple having a child with hemophilia. Mother Father -carrier of -does not have hemophilia hemophilia -genotype XHX -genotype XY Mother. XH. Xh Father Probability of offspring having hemophilia: OFocus
Marly is doing a paternity test to determine who could be her father. She is going just off of word of mouth for now so there is no way for her to figure out the genotypes of ther potential fathers. She knows for certain that she is type A with the genotype (A^I A^i). Her potential fathers are Gayle who is a Type O, Jake who is type A,and Mark who is Type AB. Who could be the potential father?
Greg is color blind and marries Susan, who is a carrier for color blindness. Color blindness is an X-linked, genetic trait. Draw the Punnett square for their children. Label each individual in the chart with their actual or predicted genotype. Fill input: Fill input: Fill input: Fill input: Fill input: Fill input: Fill input: Fill input: XX X Xy y xy X Xx Is there any chance they could have a son who is not color blind? If so, what is the probability of Greg and Susan having a son with normal vision? What is the probability of Greg and Susan having a color-blind daughter?
A man with X-linked color blindness marries a woman with no history of color blindness in her family. The daughter of this couple marries a normal man, and their daughter also marries a normal man. What is the chance that this last couple will have a child with color blindness? If this couple has already had a child with color blindness, what is the chance that their next child will be color blind?
In humans, the allele for normal blood clotting, H, is dominant to the allele for hemophilia, h. The trait is X-linked. A female hemophiliac has a child with a man who is not a hemophiliac. What is the probability that this couple's child is a hemophiliac and what is the child's gender? Your response must include a Punnett square with correct nomenclature.
