3. Construct a pedigree chart by following the information given below. A man who is heterozygous for an autosomal dominant trait marries a woman who is unaffected by that trait. Suppose they have 5 children in this order: affected son, unaffected son, affected daughter, unaffected son and unaffected daughter. The youngest daughter married a man who does not carry the gene for the trait. They have 2 children, one boy and one girl. The eldest child of the generation I couple, on the other hand, married a woman who also exhibits the trait. They have 3 children, 2 girls and 1 boy, all of whom show the trait. genotypes of all persons in this pedigree chart? What are the

9. Make a pedigree for each of the following situations. For each individual, write the individual's genotype (when possible) next to the individual's symbol (e.g. O xty, I Gg): a. Two parents do not have cystic fibrosis and they have a daughter with cystic fibrosis and a son who does not have cystic fibrosis. The daughter grows up and she mates with a male who does not have cystic fibrosis. Their only child is a boy and he has cystic fibrosis. b. A man with hemophilia mates with a female without hemophilia. They have one son and one daughter. The daughter has hemophilia and the son does not have hemophilia. The son grows up, and he marries and mates with a female. Their only child is a boy, and he has hemophilia.

I.TRUE OR FALSE: Write TRUE if the statement is correct and FALSE if it is not. Write your answers on the spaces provided. (1-10, 2 points each) 1. During mitosis one, cell divides once to form six identical cells. 2. Mitosis is divided into five phases. 3. The major purpose of mitosis is growth and to repare worn out cells. 4. In prophase of mitosis the chromosomes condense into Y-shape structures that can be easilt seen under a microscope. 5. In interphase stage of mitosis a membrane forms around each set of chromosomes ta create two new nuclei. 6. In interphase I of meiosis, the paired chromosomes line up. 7. In prophase Il of meiosis, it is visibly obvious that replication has not occurred. 8. In telophase I of meiosis, the cell pinches and divides. 9. HomologOUs Chromosomes contain the unmatched alleles donated from mother and father. 10. In anaphase of mitosis, the sister chromatids are pulled apart by the mitotic spindle which pulls one chromatid to one pole and the chromatid to…
. A sex-linked recessive allele c produces a red–green color blindness in humans. A normal woman whose father was color blind marries a color-blind mana. What genotypes are possible for the mother of the color-blind man? b. What are the chances that the first child from this marriage will be a color-blind boy? c. Of the girls produced by these parents, what proportion can be expected to be color blind? d. Of all the children (sex unspecified) of these parents, what proportion can be expected to have normal color vision?
Color blindness in humans is controlled by an X-linked completely recessive allele (Xc), while breast cancer is controlled by an autosomal completely dominant allele, B. A color blind male, who is a heterozygote carrier for breast cancer has three children/n with a normal eyed female (whose mother was color blind), who is homozygote recessive for the breast cancer allele. What is the probability that out of three children, 2 will be color blind males, and not show breast cancer, and one will be a color blind female, who shows breast cancer?

Could this trait be inherited as a simple autosomal recessive? YES oo 8995 ON b. Could this trait be inherited as a simple autosomal dominant? YES ON C. Could this trait be inherited as a simple x linked recessive? YES ON d. Could this trait be inherited as a simple x linked dominant? YES ON e. Could this trait be inherited as a Y linked? YES ON
