The accompanying pedigree below shows a family in which an autosomal recessive disorder is present. Family members I-2 and II-2 are affected by the disorder and have the genotype dd. A pregnancy involving II-4 has just undergone genetic testing for a VNTR that is linked to the disease gene. The VNTR has a recombination frequency of r = 20 with the disease gene. The VNTR has two alleles, V₁ and V₂. The gel electrophoresis patterns for each family member are shown, including the VNTR genotype for II-4. Based on the information given, answer the following questions about the family. Excluding II-4, what is the genotype of each family member for the disease gene?

Hello, everyone. Here we have a question that says if the female is the carrier, about half the sons are affected. If the female is home Messias, 50% of the daughters and 100% of the sons can be affected. Which of the following types of traits? Does it determine A Y chromosome linked traits? Be excellent recessive traits, C X linked, dominant traits or the autism or recessive traits? X linked recessive traits are passed down from the mother to her sons. And if the females are the carrier, about half the sons will be affected. However, if the females homocide agus, then 50% of the daughters and 100% of these sons can be affected. So our answer here is B explain recessive traits. Thank you for watching. Bye.
