Answer #1

Question 07 A

Answer: Autosomal Recessive Disorder.

Explanation: In this given pedigree it can be seen that while the parents are unaffected their children show the disease. Or while the parents are affected the offsprings show no disease. Therefore, we can observe the recessive characteristic.

Question 07 B

Answer:

  • I - 3: Aa
  • II - 5: aa
  • III - 1: Aa / AA

Explanation:

See the pedigree drawn in the image:

AAA 0 aa I Aa Aa OTO aa aa Aa Aa Aa Aa Aa har AAA aa aa A. LIKELY MODE OF INHERITANCE is AUTOSOMAL RECESSIVE. B. I-3 – Aa I-5

    For each pedigree below determine the most likely mode of inheritance and label each individual with a genotype. If you know they have a dominant phenotype, but don’t know the genotype, then label them with both possibilities. Please use the alleles A and a. Modes of inheritance for these pedigrees are autosomal dominant or autosomal recessive. For each pedigree determine if the alternative mode (not the one you chose) is also possible. female = male = III 4 6 IV...
