MBG 2040 / MBG2040 QUIZ 1 ANSWERS Question 1 0 / 1 point In pea plants round seeds are dominant over wrinkled. The gene responsible for this trait exhibits typical Mendelian expression and is designated with a D for the dominant allele and with a d for the recessive allele. If two heterozygote plants are crossed (Dd x Dd) this would be considered a _ . Homozygous Cross Dihybrid Cross Heterozygous Cross Question 2 0 / 1 point In reference to the pedigree above, what ...

MBG 2040 / MBG2040 QUIZ 3 ANSWERS Question 1 0 / 1 point The separation of Sister Chromatids occurs in which of the following processes? i.Anaphase of Mitosis ii.Meiosis I iii.Meiosis II iv.Telophase I v.Telophase II vi.Anaphase I vii.Anaphase II None of the above i and iii iii only i, iii and vii ii only iii and v i, ii and vi Question 2 0 / 1 point One chromosome which has undergone duplication and consists of two sister chromatids is referred to as: A Univ...

MBG 2040 / MBG2040 QUIZ 2 ANSWERS Question 1 Inbred lines of self-fertilizing plants are typically homozygous for many genes and are often less vigorous than hybrid lines, this is referred to as: Inbreeding Depression Heterosis Hybrid vigour Allelism Question 2 Fatal Familial Insomnia is an inheritable prion disease caused by a mutation in the gene (PrPC) encoding the human prion protein (hPrP). The mutated allele (PrPSC) codes for a prion protein that replaces the typical α-h...

MBG 2040 / MBG2040 QUIZ 4 ANSWERS Question 1 The process in which chromosomes exchange material through the breakage and reunion of their DNA molecules is called: Crossing Over Gene linkage Replication Assortment Question 2 In regards to linked genes, a dihybrid genotype can occur in two configurations cis and trans, however the configuration of the alleles has no impact on the gametes produced by the dihybrid individual. False True Question 3 The genes for red hair and freckles both ...
