- Notation: D = disease allele at gene d = wild-type allele at gene Let’s provide some information about each MOI. AD: Each of the F1 parents is heterozygous for the D allele. SLR: The observed F2 data are the offspring from an F1 cross where the father is affected (disease) and the mother is an unaffected carrier (wild-type, or WT). That is, the mother’s genotype has one disease allele and one WT allele in it. In Table 1, I provide the observed data counts (in dark blue). Notice that I stratify by gender.

Determine the genotypes of the parents and their children when albino male and normal femaleI'm having trouble with my genetics study guide, and am stuck on this question. If someone could explain it with the work it would help me so much. Thank you! In humans, the inheritance of the ABO blood group system exhibits both complete dominance (alleles IA and IB are dominant to allele i) and codominance (alleles IA and IB). In addition, thalassemia shows incomplete dominance; heterozygotes (Tt) exhibit a mild form of the disease (thalassemia minor) and homozygotes (tt) have a more severe form (thalassemia major). A man has blood type A and his mother has blood type O. His wife has blood type AB. Both members of the couple have thalassemia minor. What is the probability that they will have a child with: a. thalassemia minor and blood type A? b. no anemia and blood type AB? c. thalassemia major and blood type B?
