A single nucleotide polymorphism in a gene encoding a core structural collagen protein causes an organism to exhibit fragile blood vessels, hyper-flexible joints, poor eyesight due to lens dislocation, and structural weakness in the cardiac valves. This multi-system clinical manifestation is a classic demonstration of:

During embryonic development in a mammalian model, a mutation completely knocks out the function of the transcription factor SOX9. However, the embryo’s karyotype is normal (46,XY), and its SRY gene on the Y chromosome is perfectly intact and actively transcribed. What will be the developmental fate of this embryo’s indifferent bipotential gonads?

During a cellular analysis of gametogenesis in a heterozygous organism (Aa), a researcher observes an error where the sister chromatids of the chromosome carrying the A allele fail to separate during Meiosis II, dragging both copies into a single resulting sperm cell. How does this mechanical error directly impact Mendel’s Law of Segregation for this specific gamete?

In an experimental grain crop, seed weight is controlled by two duplicate genes acting additively (9:6:1). Double homozygous dominant plants (AABB) produce heavy seeds, double homozygous recessive plants (aabb) produce ultra-light seeds, and individuals carrying a dominant allele at only one locus (A_bb or aaB_) produce intermediate-weight seeds. If you cross two dihybrid plants (AaBb x AaBb), how many out of 16 expected offspring will display the intermediate seed weight phenotype?

A cohort of 100 mice all share the exact same homozygous mutant genotype (mm) for a specific gene that controls tail development. Upon physical examination, 15 of these mice have perfectly normal, long tails. Of the remaining 85 mice, some have short stubby tails, others have kinked tails, and a few have no tails at all. Which statement correctly breaks down this genetic phenomenon?

If AI is detected and you receive a zero grade, it is up to the student to request a video conference, with the professor within seven (7) days, to address this issue and determine if there is a violation of the FIU Code of Student Conduct.  If a meeting is not requested within 7 days from the date the  zero score was entered, then the student will waive their right to discuss the grade and the zero grade will stand.

If AI is detected, even for reviewing or rewording the submission, it is considered a violation of the academic integrity policy, since AI was utilized.

FIU Online expects that all members of its academic community adhere to the highest ethical and professional standards. To ensure that we maintain academic integrity, we have developed policies and procedures designed to support academic excellence and intellectual growth. Academic dishonesty undermines the educational experience for everyone, and we ask that all FIU Online students familiarize themselves with rules and policies concerning academic misconduct.

An Erlang distribution models a random variable as the time elapsed before a fixed number of successes occur; for instance, one might model the time a commuter waits for their subway car as an Erlang distributed random variable. For
