- As it turned out, one of the tallest Potsdam Guards had an unquenchable attraction to short women. During his tenure as guard, he had numerous clandestine affairs. In each case, children resulted. Subsequently, some of the childrenwho had no way of knowing that they were relatedmarried and had children of their own. Assume that two pairs of genes determine height. The genotype of the 7-foot-tall Potsdam Guard was A9A9B9B9, and the genotype of all of his 5-foot clandestine lovers was AABB. An A9 or B9 allele in the offspring each adds 6 inches to the base height of 5 feet conferred by the AABB genotype. a. What were the genotypes and phenotypes of all the F1 children? b. Diagram the cross between the F1 offspring, and give all possible genotypes and phenotypes of the F2 progenyA pedigree analysis was performed on the family of a man with schizophrenia. Based on the known concordance statistics, would his MZ twin be at high risk for the disease? Would the twins risk decrease if he were raised in an environment different from that of his schizophrenic brother?The e-gram (graph to the right of allelic ladder image) and above is from a woman. She has variations 14 and 15 at STR D3S1358. If she has children with a man who has variations 12 and 19 at the same STR, what are the possible combinations of variations that their children would have?
- True False One heritable factors such as recessive form could mask the presence of the alternate allele which is in dominant form A Punnett square is used to predict the genotype and the phenotype of an offspring after a genetic cross. Mendel's law of dominance states that "when parents with pure and contrasting traits are crossed together, only one form of trait appears in the next generation." A homozygous individual could have a "Ee" as genotype DNA has a ribose sugar. G..pdf rerA group of people are studiedd with made up blood types AZ blood group which is a blood type controlled by a single gene with two loci. Indivuals in this group may be “D” ( = that their homozygous for the “D” allele) “Z” = homozygous for the “z” allele. *DZ= Heterzygous ** Total Number of people with each type 102 people have D type blood 96 have blood type DZ 31 people in this group have type “Z” QUESTION Now please calculate the allele frequencies of “D”and “Z” In doing so use variable “P”= to represent “D” allele And “q”= to represent “Z” allele Calculate the genotype frequencies expected in the population based of the q and p frequencies you calculate. A)frequency of the “Z” allele in the population ________ B)Frequency of the “D” allele in the populations__________ C)A number of expected individuals with the “DD” genotype in the population? __________ D) NUMBER OF EXPECTED INDIVIDUALS WITH THE “ZZ” GENOTYPE IN THE POPULATION?_______ E) A NUMBER OF EXPECTED…In addition to the allelic pair determining pattern baldness in man (B,b), consider early baldness to be due to another autosomal allele (E) on a different pair of chromosomes and also dominant in males but recessive in females. The phenotype for ee may be late or nonbaldness depending on sex and the genotype for B, b alleles. Two doubly heterozygous persons marry. What is the phenotype of the male parent? What is the phenotype of the female parent? Give the phenotypic ratio expected among male children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio. Give the phenotypic ratio expected among female children of couples such as this one. Show corresponding genotypes for each phenotype mentioned in your phenotypic ratio.
- If one parent is heterozygous for blood type B and the other parent is blood type AB , what are the possible blood types of the children? For reference, the alleles possible for blood typing are: IA |B i О А, В, АВ, О B or O A or B О А, В, АВ O A or Oк, х Ааv AdBbCc AaBbCc No Spacing AaBbCc 三、相、 1 Normal Heading 1 Font Paragraph 6. Let's assume that the non-taster, daughter in question 5 is a carrier of the albino trait. She marries a Styles taster man, normally pigmented, whose mother was a non-taster albino. Show the cross between these parents. Genotype of the woman Genotype of the man Genotypes Phenotypes What is the chance that their child will be a taster? Footer What is the chance that their child will be albino? What is the chance that their child will be a taster albino? J.S.)A couple is going to have a baby. They are concerned about sickle cell anemia, which results from having the homozygous recessive combination of the sickle cell gene ("s"), which produces abnormal hemoglobin. Having at least one normal version of the gene ("S") results in normal hemoglobin. The woman is heterozygous, and so is the man. What alleles does mom have? What alleles does dad have?
- 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.Human ABO blood type is controlled by the I locus and has three possible alleles. The alleles which code for type A blood (IA) and type B blood (1³) are codominant, while the allele for type O blood (i) is recessive. In a cross between a person with a genotype of lªi and a person with genotype I³i, what is the probability of having three offspring with type 0 blood? O 1/4 O 1/32 O 1/64 O 1/8 O 1/16Adenike and her partner, Debare, are expecting their first child. Adenike is healthy as are her two sisters but her brother has PKU, a recessive disorder of the PAH gene. Genotypically he must be pah-/pah-. Neither of Adenike's parents has PKU but both of her grandmothers did. Debare is a carrier of Sickle Cell trait, which means he has one allele for wildtype hemoglobin (HbA) and one allele for Sickle Cell (HbS), making him HgA/HbS. More importantly, he has two alleles for Marfan Syndrome, a pleiotropic dominant disorder that can affect up to 30 different traits (M+/M+). No one in Debare's family has ever had PKU and no one in Adenike’s family has ever had Sickle Cell or Marfan Syndrome. They consult a genetics counselor over concern of the health of their baby. The genetics counselor collects the medical histories of three generations; their grandparents, their parents, and them. In her calculations, she produces a phenotypic key that indicates M = Marfan, Hb = sickle cell, and pah-…
