Question

LABORATORY 10: INHERITANCE END-OF-EXERCISE REVIEW MATCHING: Choose the modes of inheritance listed at the right that correspond to the statements at the left. Each inheritance type will be used twice. 1. When two or more genes determine a single trait. A Incomplete dominance 2. When a trait is determined by genes located on 3. When one gene controls the expression of a B. Sex-linkage C. Polygenic inheritance D. Pleiotropy E. Epistasis F. Linked genes one of the sex chromosomes. second gone. When heterozygous individuals exhibit a phenotype that is intermediate between the phenotypes expressed by homozygous individuals. 5. When one gene controls two or more phenotypic traits. 6. When two or more genes are located closely on the same chromosome and are frequently inherited together oval radishes are crossed, the resulting offspring are 1 round: 2 oval: 1 long. This is an example of 8. Almost all cases of Duchene muscular dystrophy occur in boys. If a woman who is a carrier for this trait has a son with a normal male, there is a 50% chance that this son will inherit the genetic condition. This is an example of: children also have medium skin tone, although one child is darker than either parent and one child is lighter than either parent. This is an example of 9. An African American couple of medium skin tone has five children. Three of the phenotype effects such as a weakened aorta, nearsightedness, and deformity of the breast bone. This is an example of 10. A single gene causes Marfan syndrome that includes several seemingly unrelated kneecaps. The nail-patella gene and the ABO blood group gene are both located on chromosome 9 and tend to be inherited together. This is an example of 11. Nail-patella syndrome is a dominant condition causing deformities in nals and influences development of the auditory nerve. Absence of a dominant allele for either gene will result in deafness. This is an example of 12. One gene in humans controls normal development of the inner ear and a second gene 19 Laboratory 10: Inheritance
