Summary Introduction
To determine: The proportion of the sons that will have hypophosphatemia?
Introduction: Hypophosphatemia is an electrolyte disorder that includes there is a low level of phosphate in the blood. The signs involve dizziness, trouble in breathing, and lack of appetite. Also, complications constitute seizures, unconsciousness, rhabdomyolysis, and weakening of the bones.

Julie (a female) has hemophilia. Based on
this information, what can we say about the
genotypes of her parents?
If Julie has children with a normal male,
what is the chance that her sons have
hemophilia?
What is the chance that her daughters have
hemophilia?
A condition called Alport syndrome is
caused by a dominant X linked allele. Males
who have this condition usually have kidney
failure, while females who are heterozygous
for the condition have blood in the urine, but
usually do not have kidney failure. A male
has this condition and has children with an
unaffected female
What percent of his daughters will show any
of the symptoms?
What percent of his sons will show any of
the symptoms?
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?
an unaffected woman who is heterozygous for the x linked allele causing duchenne muscular dystrophy has children with a normal man. What is the probability that their first child is an unaffected daughter and their second child is an affected son?

- A color-blind man marries a woman with normal vision whose father was color-blind. Remember that color-blindness is an X-linked recessive trait. Hint: see figure 12.7 in book. A) What is the probability that their first child will be a color-blind daughter? B) What is the probability that their first son will be color-blind?arrow_forwardIn humans, the ABO blood type is under the control of autosomal multiple alleles. Color blindness is a recessive X-linked trait. If two parents who are both type A and have normal vision produce a son who is color blind and is type O, what is the probability that their next child will be a female who has normal vision and is type O?arrow_forwardIn humans, the ABO blood type is under the control of autosomal multiple alleles. Color blindness is a recessive X-linked trait. If two parents who are both type A and have normal vision produce a son who is color-blind and is type O, what is the probability that their next child will be a female who has normal vision and is type O?arrow_forward
- Hemophilia is another example of an X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia?arrow_forwardIn humans, the allele for normal blood clotting, H, is dominant to the allele for hemophilia, h. This is a sex-linked trait found on the X chromosome. A woman with normal blood clotting has four children: a normal son, a hemophiliac son, and two normal daughters. The father has normal blood clotting. What is the genotype for each member of the family?arrow_forwardAn X-linked dominant allele causes hypophosphatemiain humans. A man with hypophosphatemia marries anormal woman. What proportion of their sons will havehypophosphatemia?arrow_forward
- Hemophilia A is caused by a recessive X-linked allele that encodes a defective form of a clotting protein. If a affected father and a mother who is known to not be a carrier have children, what percentage of female offspring will have hemophilia?arrow_forwardA mother is heterozygous for the X-linked gene for colorblindness and also heterozygous for the autosomal inherited sickle cell anemia. She is married to a man who can see color normally and who is heterozygous for sickle cell trait. Using b (colorblind), B (normal color), S (normal hemoglobin), s (sickle cell), answer the following: a. What are the genotypes of the parents? b: What is the probability of having a child who is both color blind and has sickle cell anemia?arrow_forwardA WOMAN IS HETEROZYGOUS FOR TWO HARMFUL RECESSIVE ALLELES IN DIFFERENT CHROMOSOMES, ONE FOR PHENYLKETONURIA (PKU) AND THE OTHER FOR CYSTIC FIBROSIS (CF). SHE MARRIES AN UNAFFECTED MAN WHO IS A CARRIER FOR NEITHER DISEASE. IF SHE HAS A DAUGHTER, WHAT IS THE PROBABILITY THAT THE CHILD WILL CARRY NEITHER OF THE RECESSIVE ALLELES? EXACTLY ONE? BOTH?arrow_forward
- Hemophilia is caused by an X-linked recessive mutation in humans. If a man whose paternal uncle (father's brother) was a hemophiliac marries a woman whose brother is also a hemophiliac, what is the probability that their first child will have hemophilia? (Assume that no other cases of hemophilia exist in the pedigree.) 1/3 0 1/8 0 1/4 1/2arrow_forwardIn humans, the allele for normal blood clotting (H) is dominant to the allele for hemophilia. This is a sex-linked trait found on the X chromosome. A woman with normal blood clotting has four children: a normal son, a hemophiliac son, and two normal daughters. The father has normal blood clotting. What is the probable genotype for each member of the family?arrow_forwardA man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. a) How many of their daughters might be expected to be color-blind dwarfs? b)What proportion of their sons would be color-blind and of normal height? c)They have a daughter who is a dwarf with normal color vision. What is the probability that she is heterozygous for both genes?arrow_forward
