Affected males = XcY
Normal males = XY
Affected females = XcXc
Normal females = XX
Carrier females = XcX
XcY = 1% = 0.01
Xc = 0.01
X = 1 - Xc = 0.99
Carrier females = XcX = 2 × 0.99 × 0.01 = 0.0198 = 1.98%
Option C
Please rate high.

7: Hemophilia A, is an X-linked recessive human disorder of blood clotting with a prevalence of 1/4000 males. What is the frequency of the hemophilia allele in this population? A) .05 B) .0158 C) .0005 D) .00025 E) .000000625
Hemophilia A is a genetic disorder of recessive X chromosome mutation of the Factor VIII gene that causes a blood clotting protein Factor VIII missing or deficient. If a person with XY chromosomes is affected by Hemophilia A and a person with XX chromosomes is an unaffected person, what is the probability that their male offspring might be hemophilic and what is the probability that their female offspring might be carriers of the mutated gene?
Name Sex-linked traits are genetic char segments of DNA found on chromosomes that Sex-Linked Traits Senetic characteristics determined by genes located on sex chromosomes. Genies are and on chromosomes that carry information for protein production and that are sponsible for the inheritance of specific traits Genes exist in alternative forms called alleics. or a trail is inherited from each parent Like traits originating from genes on autosomes (non-se chromosomes), sex-linked to omosomes), sex-linked traits are passed from parents to offspring...
16. So far we have been dealing with alleles found on autosomal chromosomes. These chromosomes contain all the genetic information that is not gender related. As a human, you have 44 autosomal chromosomes (22 pairs → 11 chromosomes from your Mom and 11 chromosomes from your Dad). You also contain a pair of sex chromosomes. These chromosomes contain all the genetic information related to your gender. If you are female, you received an X chromosome from your Mom and an...
1. People wit h the sex-linked genetic disease, hemophilia, suffer from excessive bleeding because their blood will not clot. Tom, Mary, and their 4 daughters do not exhibit symptoms of hemophilia. However, their son exhibits symptoms of hemophilia because: A) Tom is heterozygous B) Tom is homozygous C Mary is homozygous D) Mary is heterozygous E All of the above are equally likely What is the risk of having a child affected by disease with an autosomal recessive inheritance both...
I need answers for 5 to 8. thank you

Fill in XY female Cri du Chat Down syndrome XX male Anhydrotic ectodermal dysplasia Patau syndrome Hemophilia Polydactyly Phenylketonuria Achondroplasia Alkaptonuria a) Develop male structure, but experiences infertility b) Develop female structures but may not have ovaries c) Female heterozygotes...

10. Hemophilia is a sex-linked disorder. A normal woman whose father was hemophiliac marries a man who is not homophiliae What percentage of their son would be would be expected to be hemophiliac? What percentage of their daughters word expected to be hemophiliacs? Again, show your work, using a Punnett Square 11. Given parents with the genotypes AaBbCcDdEe and AaBbccDdEe. what is the probability of them producing offspring with the genotype of AABCDE 12. In humans, widow's peak...
0 b) 0.21 c) 0.42 d) 0.49 e) 0.91 Problem 3: in humans, Rh-positive individuals have the Rh antigen on their red blood cells, while Rh. negative individuals do not. If the Rh-positive phenotype is produced by a dominant gene (A), and the Rh negative phenotype is due to its recessive ailele (a). what is the frequency of the Rh-positive allele if 84% of a population is Rh-positive? a) 0.04 b) 0.16 c) 0.48 d) 0.60 e) 0.84 Problem 4:...
