- Classical hemophilia is a sex-linked disease caused by a recessive gene on the X chromosome. (Hemophilia refers to diseases that cause delays in blood clotting.) If a woman who is acarrierof classical hemophilia has children with a normal male, give the ratios of the possible offspring with respect to classical hemophilia. Be sure to state both the genotypes and the phenotypes of each offspring. For genotypes, use X for a normal X chromosome, Xh for an X chromosome with the hemophilia gene, and Y for a normal Y chromosome. For phenotypes, if the offspring is female, be sure to state if homozygous normal, a carrier, or has the disease. If the offspring is a male, be sure to state if normal or has the disease.Blood type shows codominance in humans. What are the blood types for offspring born to a female with the genotype AO and a male with the genotype BO?A child has type O blood. The mother has type B blood. The mother has a paternity suit against a man with type A blood. Could this man be the child's father? What is the genotype of the child, mom, and father?
- Predict the possible genotypes for children of a couple with the blood types AB (Genotype IAIB) and A (Genotype IAio).Determine the genotypes of the parents if the father is blood type A, the mother is blood type B, the daughter is blood type O, one son is blood type AB, and the other son is blood type B4:33 4 Alger Edit Today 4:31 PM O LIVE Which of the following statements regarding Mendel's observations and Laws are still true and part of our knowledge of genetics today? (Check all that true.) M Two alleles segregate during meiosis, ending up in different gametes. Each pea plant has 2 alleles for every gene, but only contributes one in each gamete. The recombination of alleles in a zygote is completely random. The Law of Independeht Assortment was determined by following three traits in pea plants, TMendle was able to determine his Law of Segregation by following ane trait in pea plants. Every offspring inherits only 1 allele from each parent.
- If a girl has blood type AB and her mother is also AB, what are the genotype(s) and corresponding phenotype(s) of any male who could not be the girl’s father?A couple are both phenotypically normal but their son suffers from hemophilla, a sex linked recessive disorder. What fraction of their children are likely to suffer from hemophilia. what fraction are likely to be carriers.c) What blood types could be observed in children born to a woman who has blood type A and a man who has blood type AB? Draw a Punnett square to prove your answers.
- A woman has a daughter. There are three men whom she claims might have been the father of the child. Her blood type is A,her child's is B. She has three candidates for fatherhood. Their blood types are Man#1, B,Man#2, AB, Man#3, O. Based on blood types the mother claims that this proves that Man#1 must be the little girl's father. Is the mother correct? Why or why not?The gene for polydactyly (P) is autosomal and dominant to normal fingers (p). Hemophilia is sex-linked and recessive (X h ). A man and his wife both of whom are polydactylous and have normal red blood cells have a child who is non-polydactylous and with hemophilia. What are their genotypes?Two people who have normal skin color produce a child who is albino (aa). What is the genotype of each parent? O a. Father: Aa, Mother: AA O b. Father: AA, Mother: AA Father: Aa, Mother: Aa
