3) The most likely inheritance pattern in the pedigree above is:

What is the mode of inheritance of the trait caused by the topoisomerase mutation? (You may wish to work out punnet squares to determine the correct mode.) B. B Topoisomerase 1 Defect 5 O X-linked Dominant O X-linked Recessive Autosomal Dominant Autosomal Recessive 1 7 11 8₂ 15 7 13 4 Bo

For the pedigree shown here, the disorder is caused by a recessive (g) allele on the X chromosome. Label each of the following individuals with the correct genotype (XGY, XgY, XGXG, XGXg, XgXg). a. Generation I, number 2 b. Generation II, number 2 c. Generation II, number 5 d. Generation III, number 2 e. Generation III, number 6

A turkey farmer is worried about a new disease that is found in his birds. If affects females more than males. Which of the following is(are) reason(s) that explain this finding? The disease is sex linked b The disease is autosomal recessive  c The disease is located on the Z chromosome d A and C e B and C

I understand that Phenylketonuria, or PKU is recessive and that by looking at the pedigree analysis that Ryan and Natalie are mother/son, but I don't understand the genotypes for Max and Kate.   Thanks for any help.

2) Answer the following questions given the pedigree below. Please assume that no other mutations are occurring, complete penetrance, and that the individual marked with an asterisk (*) doesn’t carry the allele causing the affected phenotype. Q3) What is the probability that individual IV-1 will be a carrier? Please explain your answer.

What is the difference between polygeny and pleiotropy?

26. The trait represented in the following pedigree is expressed only in the males of the family. Is the trait Y linked? Why or why not? If you believe that the trait is not Y linked, propose an alternative explanation for its inheritance. 1 2 II 3 6 II I 2 3 4 5 6 7 8 IV 1 2 Pierce, Genetics: A Conceptual Approach, 7e © 2020 W. H.

5. The pedigree below traces the inheritance of Albinism, a genetic disorder. Affected individuals, indicated here by the coloured circles and squares, are unable to make a normal amount of melanin, the chemical that is responsible for eye, skin, and hair colour. Does Albinism appear to be caused by a dominant allele or by a recessive allele? Fill in the genotypes of the individuals whose genotypes can be deduced. What genotypes are possible for each of the other individuals? Explain! Naruto Hinata Reiner Asta Hange Mikasa Eren Historia Luffy Nezuko Zenitsu Tanjiro Son Goku

What is the probability of Sister 3 as a carrier of the death gene?
