- In 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_forwardGene “A” and gene “B” are not linked. Each has two alleles. The A allele is dominant over the a allele and the B allele is dominant over the b allele. Answer the following questions about a dihybrid (two-trait) cross. A) List all of the possible gametes (eggs) that could be produced by an individual with the genotype: aabb B) List all of the possible gametes (sperm) that could be produced by an individual with the genotype: AaBB C) Fill out a Punnett square for the dihybrid cross cross between the two individuals listed above (aabb x AaBB). What percent of the offspring from this cross would have the dominant phenotype for both traits?arrow_forwardThe genotype of EB27 and EB67 are unknown. Based on pedigree, what are the most likely genotype of each individual?arrow_forward
- Joanne has AB blood and Henry has AB blood. They have one child with A blood, one child with AB blood, and another child that has O Bombay phenotype blood. Please explain what is happening here. What is the chance that Joanne and Henry will have a child with B blood type? What is the name of the phenomenon that is responsible for the Bombay phenotype?arrow_forwardA light-haired man has blood type O, his wife has dark hair and blood type AB, but her father had light hair. Assume dark hair (H) is dominant to light (h). What is the probability they will have a child with dark hair and blood type A? What is the probability they will have a child with light hair and blood type B? What is the total number of phenotypes their children could show?arrow_forwardJulie (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?arrow_forward

Which individual in the pedigree can donate blood to all the other individuals in the pedigree?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_forwardA couple who are a carrier of sickle-cell disease with blood type A for the female and type B for the male (assume heterozygosity for blood types).

- Several genes in humans in addition to the ABO gene(I) give rise to recognizable antigens on the surface ofred blood cells. The MN and Rh genes are two examples. The Rh locus can contain either a positive or anegative allele, with positive being dominant to negative. M and N are codominant alleles of the MN gene.The following chart shows several mothers and theirchildren. For each mother-child pair, choose the fatherof the child from among the males in the right column, assuming one child per male.Mother Child Malesa. O M Rh(pos) B MN Rh(neg) O M Rh(neg)b. B MN Rh(neg) O N Rh(neg) A M Rh(pos)c. O M Rh(pos) A M Rh(neg) O MN Rh(pos)d. AB N Rh(neg) B MN Rh(neg) B MN Rh(pos)arrow_forwardTwo people are planning to have children together. Each person is heterozygous for the gene “A”. Using this letter, first list all the possible gametes that the two people can produce. Next, write all the possible genotypes and phenotypes for their offspring, using the correct genetic terminology (e.g., “genotype is homozygous dominant” “phenotype is dominant”). HINT: Use the gametes to construct a Punnett square and predict the possible offspring (you do not need to include the Punnett square in your answer).arrow_forwardAlbinism in humans is inherited as a simple recessive trait.Determine the genotypes of the parents and offspring for the following families. When two alternative genotypes are possible,list both.(a) Two parents without albinism have five children, four withoutalbinism and one with albinism.(b) A male without albinism and a female with albinism havesix children, all without albinism.arrow_forward
