In humans, XO individuals are females with Turner syndrome and XXY individuals are males with Klinefelter syndrome. Red-green color blindness is caused by an X-linked recessive allele. Suppose a color-blind man and a woman with normal vision and no family history of color blindness had a daughter who was color blind and had Turner syndrome. Which event could have given rise to this offspring? Nondisjunction at meiosis I in the mother Nondisjunction at meiosis II in the mother Nondisjunction at meiosis I in the father Nondisjunction at meiosis II in the father Nondisjunction at either meiosis I or meiosis II in the mother

A color-blind woman with Turner syndrome (XO) has a father who is color blind.Given that the gene for the color-blind condition is recessive and X-linked, provide a likely explanation for the origin of the color-blind and chromosome constitution in the color-blind woman. nondisjunction in the mother in meiosis I or II nondisjunction in the father at meiosis I no abnormalities had to occur to produce this daughter nondisjunction in the father in meiosis I or II nondisjunction in both the mother and father in meiosis I.
Red–green color blindness is a human X-linked recessive disorder. A young man with a 47,XXY karyotype (Klinefelter syndrome) is color blind. His 46,XY brother is also color blind. Both parents have normal color vision. Where did the nondisjunction that gave rise to the young man with Klinefelter syndrome take place? Assume that no crossing over took place in prophase I of meiosis.
An individual that is homozygous AABBcc is crossed to an individual that is homozygous aabbCC producing F1 individuals with genotype AaBbCc. Assume that the A, B, and C loci are all on the same chromosome. One chromatid at the start of meiosis (before crossing over) has the alleles A, B, and c. What alleles are on its sister chromatid? What alleles are on the homolog? Group of answer choices A. Sister chromatid ABc, Homolog no way to tell B. Sister chromatid ABC, Homolog abc C. Sister chromatid ABc, Homolog abC D. Sister chromatid abC, Homolog ABc
Draw a diagram of Metaphase I and II of meiosis in the father, which illustrates the only possible way in which the father’s chromosomes could have aligned during Metaphase I, and in the subsequent Metaphase II in the same cell, in order to have resulted in the conception of the specific son who has all three of these genetic conditions (achondroplasia, color blindness and deafness).
The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are male. Individuals with XO (only one X chromosome) are female. For the following family, identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the child. A man with a pointed nose and a woman with a round nose have a daughter with a round nose. This daughter has Turner Syndrome (genotype XO: one X chromosome). Nondisjunction must have occurred in melosis 2 of the mother More than one of the answers is correct Nondisjunction must have occurred in meiosis 1 of the father Nondisjunction must have occurred in meiosis 1 of the mother Nondisjunction must have occurred in meiosis 2 of the father
A woman who is homozygous for normal color vision mates with a colorblind male. they produce a female child how has only one X chromosome and who is also color blind. In which parent did the nondisjuction take place? Can you specify which meiotic division?
Very rarely, one member of a pair of identical (monozygotic) twins will have Turner syndrome (XO) and the other member will be normal (XX). Which of the following statements best explain this phenomenon. There was a non-disjunction event during mitosis in the zygote. O There was a non-disjunction event during meiosis in dad. there was a non-disjunction event during meiosis in either parent There was a non-disjunction event during meiosis in mom. Dad's X chromosome was inactivated, causing Turner syndrome.
An individual heterozygous for a reciprocal translocation possesses the following chromosomes: A B • C D E F G A B • C D V W X R S • T U E F G R S • T U V W X Q. Diagram the alternate, adjacent-1, and adjacent-2 segregation patterns in anaphase I of meiosis.
During the process of Meiosis an individual's alleles for each trait are independently sorted to make unique gametes. A person is heterozygous for the Freckles phenotype (Ff) and also heterozygous for the PTC-tasting phenotype (Tt). This person's genotype for these two traits is represented as FfTt. A) How many unique gametes could be produced by this individual if you consider these two traits? B) List the different allele combinations that could result.
Table 8.1 shows that Turner syndrome occurs when an individual inherits one X chromosome but lacks a second sex chromosome. Can Turner syndrome be due to nondisjunction during oogenesis, spermatogenesis, or both? If a phenotypically normal couple has a color-blind child (due to a recessive X-linked allele) with Turner syndrome, did nondisjunction occur duringoogenesis or spermatogenesis in this child’s parents? Explain your answer.
