QUESTION 5. The pedigree below follows the appearance of a rare autosomal dominant condition resulting in malformation of limbs through a family. What is the penetrance of this trait? i.e., What is the ratio between the number of individuals in the pedigree who display the trait (numerator) and the number of individuals you know from the pedigree must have the trait-determining genotype (denominator)? Enter your answer in the form of a fraction without any spaces. e.g., If your answer is “one-fourth”, enter: 1/4
Question:- Based on your selected mode of inheritance, show the genotypes for the following individuals. [Use these symbols for alleles: if it is autosomal, then use the symbols B - dominant, b - recessive (e.g. BB, bb etc.) if it is X-Linked, then X(B) - dominant, X(b) - recessive, and Y for Y-chromosome (e.g. X(B)X(B), X(B)Y etc.) ] I-1 I-2 II-7 II-8 III-10 III-11 III-12 IV-8 IV-9
4. Sickle Cell Anemia is an autosomal recessive trait. Given one parent is a carrier and the other parent does not carry the allele , what is the likelihood that their child will haye sickle cell anemia?
MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The Mendelian pattern of inheritance is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel’s lawsII. As an example, a characteristic may be controlled by one gene with two alleles, but the two alleles have a same relationship like the simple dominant-recessive relationship a. The first statement (I) is correct and the second statement (II) is wrong b. The first statement (I) is wrong and the second statement (II) is correct c. Both statements are correct d. Both statements are wrong MODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle.II. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce…
11. Below is a pedigree chart of an autosomal recessive disorder. Answer the following questions using the correct genetic terminology (do not just write letters like “Ee”). A. What is the genotype of individual 1 in generation II? B: What is the genotype of individual 2 in generation I?C: Is it true that individuals 6, 7, 8, 9, and 10 in generation III all have the same genotype? Why or why not?
In a mating between two individuals that are heterozygous for a recessive lethal allele that is expressed in utero, what genotypic ratio (homozygous dominant: heterozygous:homozygous recessive) would you expect to observe in the offspring? a. 1:2:1 b. 3:1:1 c. 1:2:0 d. 0:2:1

Why are genetic disorders such as hemophilia and Duchenne muscular dystrophy more prevalent in males than females? A. Because they can only be passed on from father to son B. Because they are recessive disorders C. Because they are dominant genetic disorders D. Because they are X-linked recessive disorders
