- Based off the information given, complete the table a. What mode of inheritance pattern best fits this pedigree in your opinion?arrow_forwardGive typing answer with explanation and conclusion Approximately 1 out of every 10,000 Caucasians in the USA are born with the recessive disease cystic fibrosis. If this trait is in Hardy-Weinberg equilibrium, approximately how many people are carriers?arrow_forwardGiven the pedigree below, answer the questions that follow: a. Probable mode of inheritance:b. Justification:arrow_forward
- Give written answer with explanation and conclusion A cross was made between a white male dog and two different black females. The first female gave birth to eight black pups, and the second female gave birth to four white and three black pups. What are the likely genotypes of the male parent and the two female parents? Use Punnett’s squares to support your answer. Explain whether you are uncertain about any of the genotypes.arrow_forwarda. Is the trait indicated by the solid symbols inherited in a dominant or recessive manner? (2) b. Give a definitive reason for your answer in (a). (This reason should not be skips a generation or doesn’t skip a generation). c. Assign genotypes for individuals III-3 in both pedigrees.arrow_forwardSuppose that two individuals who display toothed beaks mate and have three offspring who have toothed beaks and two who have normal beaks. Is it possible for the trait to be autosomal recessive? Why or why not? (Sketching out a quick pedigree may help you answer)arrow_forward
- If both parents are recessive short, what is the phenotype in percentage (%) for the possible offspring? Use the reference sheet below to answer.arrow_forwardBased on the data, which trait do you think is dominant versus recessive? Explain the information you used to help you determine this. Based on your answer, how would you write the genotypes of the original parental generation for this cross?arrow_forwardSuppose that for three generations, the clawed wing trait has only shown up in males. In the fourth generation, a mating between a clawed wing male and a normal wing female produces a clawed wing female. Does this necessarily mean that the trait is not sex-linked? Why or why not? (Sketching out a quick pedigree may help you answer)arrow_forward
- use the pedigree and answer : What is the genotype of the son with no white lock of hair? what is the genotype of the son with the white lock of hair? What is the genotype of the daughter with the white lock of hair ?arrow_forwardUse the image below to answer the following questions. Label the genotypes for ALL the family members in the pedigree above. Remember to use XX and XY when labeling. What does it mean to be a carrier? Why does Alexis have hemophilia? Is hemophilia a sex-linked disease? What does that mean and how does this pedigree show you this?arrow_forwardUse the pedigree to answer the question. What is Ann’s genotype for this trait? A. She must be AA. B. She must be Aa. C. She can be either aa or AA. D. She can either be AA or Aa.arrow_forward
