Answer:
b. Frank received the mutant chromosome from his father. Nondisjunction occurred in his father during the first meiotic division.
Explanation:
As you can see in the question above, Frank has Klinefelter syndrome which causes him to have normal skin patches and skin patches without sweat glands. Her mother has completely normal hair, which may indicate that the defective gene was not supplied by her. In addition, Frank's father has anhydrotic ectodermal dysplasia, an X-linked condition where the skin does not contain sweat glands.
Although Frank's father's defective gene is linked to the X chromosome, it is likely that Frank inherited the defective gene from his country. This may have occurred because during meiosis I, his father's genes did not show disjunction. As a result, Frank presents a mosaic of his phenotype, because an inactivation of the X chromosome occurred.
Answer:
A titin mutation that occurs in muscular dystrophy with myositis (mdm) mice results in a predicted 83 amino acid deletion in the N2A and PEVK regions of the titin protein. Muscles from mdm mice are actively more compliant possibly owing to the deletion in titin's I-band region. This suggests that modulation of titin stiffness in active sarcomeres by the proposed titin–thin filament interaction may be affected by the mdm mutation. The answer is YES I believe.
Explanation:
I believe the answer is yes from my deep reaserch. You may want to research in your texts book/lesson or courses and review what your teacher/professer has given you.
