Below is a pedigree of a human blinding disease. Use this pedigree to answer the following questions. If this is disease has an autosomal recessive inheritance pattern, what is the probability that if individuals IV-5 and III-5 had and offspring it would exhibit the disease? a) 25% b) 33% c) 11% d) 17% e) 6%

You do a testcross to map three genes, Ph, T, and Qc. In the table below, you will find the number of offspring that inherited each combination of alleles from the heterozygous parent.  Ph gene T gene Qc gene counts ph T Qc 304 Ph t qc 301 Ph T qc 172 ph t Qc 169 ph T qc 21 Ph t Qc 19 Ph T Qc 8 ph t qc 6   This data was also provided in the previous question. Use the data and the map you made to calculate interference.  Round to the nearest 0.001.

Below in Figure 1 is a pedigree for a family afflicted by a genetic disorder. In some populations, Cystic fibrosis has an incidence of 1 in 2500 newborns. The carrier frequency calculated from this is 1/25. Analyze the pedigree below assuming the disease is similar to cystic fibrosis in incidence and carrier frequency. However this disease may not have the same type of genetic transmission as cystic fibrosis. What type of genetic transmission is most consistent with the pedigree? Label all the individuals that you can determine, with hypothesized genotypes. Label the individuals that have unknown genotypes with possible genotypes. Assuming her father is known to NOT be a carrier, calculate the probability that IV1 is a carrier for disease. Use the Χ2 test to determine whether your proposed transmission fits this data.

In a particular breed of dog, the following genotypes and their respective phenotypes are known: ● • lect one: A. The C¹ allele is the most dominant 3. The C3 allele is the most dominant The C2 allele combination is the most dominant C1, C², and C3 are codominant C'C' = black coat C'C² = black coat • C²C²= brown coat • ● C'C' =yellow coat C'C²=yellow coat C'C'=yellow coat Which of the following conclusions is supported by the information above?

făctőrs suc 19) The genotype of a black snake is unknown. Black is a dominant allele, so the snake could be either BB or Bb. You cross this snake with a white snake (bb). Which of the following results of that cross would support the unknown genotype of the black snake being a homozygote? A) All F1 offspring are white B) All F1 offspring are black C) Half of the F1 offspring are white, the other half are black D) Three-quarters of the F1 offspring are black, the other quarter are white В x bb the

Gene dosage is important for a number of genetic phenomenon. Name two and explain their relationship to the genotype and phenotype observed.

Which of the following terms is the most broad?   a phenotype b character c trait

In one General Biology 2 class, there were 51% of the students whocould roll their tongue, having either genotype RR or Rr. What is thefrequency of the r allele?

The diagram below describes the relationships of genes, alleles, and loci of genetics and how a genotype manifests as a phenotype using the pea plant flower as an example. In this case, the genotype is heterozygous, meaning that the plant carries two different alleles of the gene. Think of a scenario where you have a pea plant that is homozygous recessive in flower color. Determine the phenotype of the flower color for this plant and describe how the phenotype is derived based on the information provided in the below diagram. Make sure to include the following terms, gene, allele, locus, enzyme, and gene expression, in your discussion.
