A. close together B. unlinked
C. linked D. on non-sister chromatids of homologues Feedback: Correct Question 18 of 40 2.5 Points Low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice. This is an example of _________.
Feedback: Learning Objective: Identify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage
Question 19 of 40 2.5 Points Nondisjunction during meiosis I will result in ________.
Feedback: Learning Objective: Explain how nondisjunction leads to disorders in chromosome number Question 20 of 40 2.5 Points What is the correct order of DNA compaction in eukaryotes?
Feedback: Correct Question 21 of 40 2.5 Points What best describes the difference between paracentric and pericentric inversion? A. the number of genes inverted
B. the number of centromeres inverted C. the placement of centromeres in the inversions D. if the inversion is on autosomal of sex chromosomes Feedback: Learning Objective: Describe how errors in chromosome structure occur through inversions and translocations Question 22 of 40 2.5 Points What does a spliceosome remove from pre-mRNA during the process of splicing?
C. spliceons D. 7-methlyguanosine E. poly-A tail Feedback: Learning Objective: Describe the different steps in RNA processing Question 23 of 40 2.5 Points In co-dominant traits, what is the phenotypic ratio when two heterozygotes cross?
D. 1:3 E. 4:0 Feedback: Learning Objective: Identify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage Question 24 of 40 2.5 Points Combination of alleles that independently assort is usually higher than the number of chromosomes because
E. gene linkage Feedback: Correct Question 25 of 40 2.5 Points Which is likely to disrupt the function of the most genes: a 500kb deletion, a 500kb inversion, or a 500kb translocation? A. Deletion B. Inversion C. Translocation Feedback: The deletion will disrupt all the genes contained within it, but the inversion and translocation will likely only affect the genes on the ends.
