Jenny, like her mother, is heterozygous for both X-linked traits. Her father suffered from both hypophosphatemia and muscular dystrophy. Jenny’s fiancé, Mark has a mother suffering from muscular dystrophy despite having normal bone conditions. His father has been blessed with strong bones and muscles but suffered from amelogenesis imperfecta

Ch. 14-9 Mutations in the genes for clotting factor VIII and IX cause hemophilia A and B, respectively. A woman may be heterozygous for mutations in both genes, with a mutated factor VIII allele on one X chromosome, and a mutated factor IX allele on the other. All of her sons should have either hemophilia A or B. However, on rare occasions, one of these women gives birth to a son who does not have hemophilia, and his one X chromosome does not have either mutated allele. Explain.
question- Color blindness is inherited as a sex-linked recessive disease. A normal male marries a female who is heterozygous for the trait. What percentage of their sons will exhibit color blindness?
Question: Black hair of the mouse is produced by dominant gene B and white hair by recessive allele b.Female with black hair crossed with male black hair (both genotypes are heterozygous). Produced individuals 112 and 113, female with white hair and male with black hair, then mating occur between 114 and 113, and another mating occur between 112 and 111. assume that 111 and 114 individuals do not carry the recessive allele, represents the above in a pedigree chart and determine the genotype of each individual.
Question:- 8. Describe how Morgan’s experiment with the white-eyed mutant fly provided evidence for the chromosomal basis for inheritance. Be sure to include the significance of the x-linked gene.
Question:- Based on your selected mode of inheritance, show the genotypes for the following individuals. [Use these symbols for alleles: if it is autosomal, then use the symbols B - dominant, b - recessive (e.g. BB, bb etc.) if it is X-Linked, then X(B) - dominant, X(b) - recessive, and Y for Y-chromosome (e.g. X(B)X(B), X(B)Y etc.) ] I-1 I-2 II-7 II-8 III-10 III-11 III-12 IV-8 IV-9
Practice Pedigree Problem help. I am confused so please show. Label Phenotypes and genotypes as you go about the Pedigree (and whatever else might be required)! Thank you again for your help, these questions confuse me). Hair or fur length in cats is controlled by a single, autosomal gene; the short hair-allele is dominant to the allele for long hair. Hair color is produced by a different gene which is located on the X chromosome. One allele for this sex-linked gene produces yellow, while an alternate allele produces black fur color; individuals which are heterozygous for these alleles are calico or tortiseshell in color. a). If a long-haired, black male is mated with a calico female homozygous for short hair, what kind of kittens will be produced in the F1generation? Give both genotypes and phenotypes; express the genotypes both symbolically and in words.
Need help, please. What are the ratios for the progeny phenotype(s)?
My Question is what is the probability their first child will have hemophilia and drawn pedigrees for family members with genotypes. My explantion so far: A man has both X and Y chromosomes as sex chromosomes in his body. Here, though the brother of the man is hemophiliac, a man can’t be a carrier of hemophilia. So, it can be said that his chromosome is “XnY”.Here, the “n” stands for “normal”.Though the paternal uncle is hemophiliac, a man cannot be a carrier of hemophilia, his niece will not be a career. So it can be said that the woman is also not a carrier and has the “XnX” chromosome.So, as the mother is not a carrier, their first child does not have a chance of having hemophilia. This can be determined as it is known that there is no hidden carrier of hemophilia in the family.
TOPIC: Sex-linked inheritance Glucose-6-phosphate dehydrogenase deficiency/G6PDD (g) is an X-linked recessive condition wherein the red blood cells of affected individuals undergo premature hemolysis. Fragile X syndrome (F), on the other hand, is an X-linked dominant mutation characterized by a mild to moderate intellectual disability. Amelogenesis imperfecta (AMELY) (A) is a sex-linked congenital disorder affecting the formation of the teeth enamel making affected individuals at higher risk for dental cavities and related problems. Only male offspring inherit this condition. Jane is heterozygous for both X-linked traits like her mother. Her father is normal for both X-linked traits. James has a mother who suffers from G6PDD but not from fragile X-syndrome. His father does not exhibit any X-linked disorder but has amelogenesis imperfecta. What are the genotypes of the following: Jane: ________ James: _________ Jane’s mother: __________…
