- Use the following information to respond to the three questions posed below: (1) The proband (affected individual who led to the construction of the pedigree) exhibits the trait. (2) Neither her husband nor her only sibling, an older brother, exhibits the trait. (3) The proband has five children by her current husband. The oldest is a boy, followed by a girl, then another boy, and then identical twin girls. Only the second oldest fails to exhibit the trait. (4) Both parents of the proband show the trait. a. Construct a pedigree of the trait in this family. b. Determine how the trait is inherited (go step by step to examine each possible pattern of inheritance). c. Can you deduce the genotype of the probands husband for this trait?What is the assignment is to provide definitions of the following five terms? A. Homozygous genotype (or homozygote) B. Heterozygous genotype (or heterozygote)Monozygotic (identical) twins share all of the same DNA, yet have differences in appearance and behavior. Explain why this is, using the following terms correctly in your discussion: genotype, phenotype, multifactorial trait.
