Question 7
Step by step
Solved in 2 steps
- Hi, I'm having trouble with my study guide for my upcoming genetics exam. If someone could please help with work shown and an explanation it would help so much! Thank you!! 2a. The pedigree below represents inheritance of rare condition. What pattern of inheritance is most consistent with the data? Assign alleles to all individuals to support your answer. If an allele is unknown, assign it a ? symbol. NOTE: Individuals whose phenotype or genotype cannot be determined are assumed to be unaffected and homozygous, unless otherwise indicated. 2b. In addition to the alleles you’ve indicated, describe 2 overall features of the pedigree that make it consistent with your chosen form of inheritance. 2c. Based on your mode of inheritance, what is the probability that the child of couple IV-4 x IV-5 will be affected? Show your work. attached is the pedigreeClick on the link: https://www.dailymail.co.uk/news/article-4168946/Mum-world-s-black-woman-two-white-babies.html#ixzz4hvs1FUeM.Links to an external site. This case explores how skin color is inherited in humans, presented in the story of Catherine and Richard Howarth whose children are surprisingly light skinned compared to their Nigerian mother. Based on what you have learned about polygenic inheritance, explain how Richard and Catherine Howarth were able to produce light-skinned babies. Are the odds indeed 1 in a million? Include possible genotypes of the couple and their children to support your argument.Klinefelter syndrome (XXY) can most be easily diagnosed by _______. a. pedigree analysis. b. aneuploidy c. karyotyping d. phenotypic treatment
- A couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the womans family but not in the mans family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?Need help, please. What are progeny genotypes and phenotypes? Include the ratio too, please.A young couple went to see a genetic counselor because each had a sibling with cystic fibrosis. (Cysticfibrosis is a recessive disease, and neither member ofthe couple nor any of their four parents is affected.)a. What is the probability that the female of thiscouple is a carrier?b. What are the chances that their child will havecystic fibrosis?c. What is the probability that their child will be acarrier of the cystic fibrosis disease allele?
- Two mothers give birth to sons at the same time at a busy urbanhospital. The son of mother 1 has hemophilia, a disease causedby an X-linked recessive allele. Neither parent has the disease.Mother 2 has a son without hemophilia, despite the fact thatthe father has hemophilia. Several years later, couple 1 suesthe hospital, claiming that these two newborns were swappedin the nursery following their birth. As a genetic counselor, youare called to testify. What information can you provide the juryconcerning the allegation?7. Mr. and Mrs. Weasley have 7 children and all of the children have red hair like their parents. Mrs. Weasley has brown eyes but Mr. Weasley's eye color is unknown. Four of their 7 children have blue eyes and three have brown eyes. a. I Mr. Weasley's eye color is blue, what must be Mrs. Weasley's genotype? Explain how you arrive at your answer. Draw a Punnett square to support your answer. ExplanationI need help on how the traits below are inherited. Either by Mendelian, Codominance, Incomplete dominance.
- Need help, please. What are the ratios for the progeny phenotype(s)?A couple has three children, all of whom have brown eyes and blond hair. Both parents are heterozygous for brown eyes (Bb), but one is blond (rr) and the other is a redhead (Rr). What is the probability that the next child will be a brown-eyed redhead? For full credit, you must show all workAttached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.
