The hemoglobin B gene (Hb) has a common allele (A) of SNP (rs 332) that encodes the HbA form of (adult hemoglobin) and a rare allele (T) that encodes the sickling form of hemoglobin, HbS. Among 571 members of the Yoruba tribe in Nigeria, 440 were A/A. 129 were A/T, and 2 were T/T individuals. Use the chi-square test to determine whether these observed genotypic frequencies fit the Hardy-Weinberg expectations.

The black color cost in hamsters is due to a dominant gene (B).. A recessive allele (b) at this locus results in a brown coat when homozygous (b/b). However, neither coat color is expressed when the organism is homozygous for the allele (a) at a separate locus. The a/a genotype results in a white (albino) coat, regardless of the allele at the B locus. The wild-type allele (+) at the (a) locus allows normal coat coloration, whether the genotype is...

Beta-thalessemia is caused by mutations in the hemoglobin B gene we discussed along with sickle cell anemia. There are some anemia-causing mutations that are dominant while other mutations act in a recessive manner. The anemia caused by either type can be debilitating in affected genotypes and would be selected against in areas which do not have malaria. a) Assuming both forms of beta-thalessemia in the affected genotypes show similar fitness relative to unaffected genotypes, which type of allele (recessive or...

Assume that another allele of the cinnabar gene, named cnx, has a 1.8 kb insertion in exon 3. Develop a PCR strategy that would discriminate between cnx and cn+ (include a schematic!); you can assume that the sequence of the cnx allele is known. Include the time you would allow Taq polymerase to synthesize the DNA. Note: In your answer you do not have to consider the cn1 allele at all!

The human gene Trl is maternally imprinted. Hannah has a heterozygous genotype include one wildtype allele and one copy of the mutant “1” allele, Trl+Trl1. Hannah expresses the mutant allele. Describe the methylation pattern of Trl alleles in Hannah’s somatic cells and in her gametes.

Gene A has two alleles, A1 and A2. Gene B has two alleles, B1 and B2. In a population, the following haplotypes are observed. A1B1 = 0.2, A2B2 = 0.45, A1B2 = 0.15, and A2B1 = 0.2. Calculate the extent of linkage disequilibrium, D.

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
