Assume no do novo (new) mutations, and assume individuals mating into the pedigree do not have the affected allele unless you have information to that tells you otherwise. What is the most likely mode of inheritance in the pedigree shown above?

Which stage of meiosis explains Mendel’s Law of Independent Assortment (i.e., that half of gametes get one gene copy, and the other half of gametes get the other gene copy)?

What are two methods that can be used to obtain genetic material from a fetus inside the uterus if diagnostic testing is necessary before birth? [answer1] and [answer2]

The normal phenotype is dominant (N), and the hemophilia C phenotype is recessive (n). A man with a normal phenotype and a woman with hemophilia C have 8 children. All 8 children are phenotypically normal. What is the most likely genotype of the father?

Melanin synthesis in the eye is determined by 2 genes. The OCA2 gene controls melanin synthesis; PP or Pp = brown color; pp = blue color. The HERC2 gene controls (“switches on”) the OCA2 gene; CC or Cc = brown color; cc = blue color. Therefore, a homozygous recessive genotype for either gene, pp or cc, results in blue eyes). What is the probability of 2 brown-eyed parents heterozygous for both genes having a blue-eyed child? [answer1]

What type of sample is needed for prenatal cell-free fetal DNA (aka non-invasive pre-natal diagnosis) testing?

A 45-year-old woman complains of persistent fatigue, constipation, and dry skin. Her thyroid gland is diffusely enlarged and firm on examination. Which combination of laboratory results would be most indicative of Hashimoto’s thyroiditis which may lead to primary hypothyroidism?
