WGU C653 HEREDITY AND GENETICS FINAL
PAPER 2026 QUESTIONS WITH FULL ANSWERS
◉ What are the structures in a cell that group genes together, are
composed of chromatin (DNA and protein), and become visible
under a light microscope during mitosis? Answer: chromosomes
◉ What might be the common features of all genomes, no matter
where they exist? Answer: -the ability to replicate the genetic
information accurately for the next generation
-the ability to store the entire set of information an organism needs
for reproduction and development
◉ Model genetic organisms Answer: ______ are organisms with
characteristics that make them useful for genetic analysis
◉ Common characteristics of model organisms Answer: -Short
generation time
-Production of numerous progeny
-The ability to carry out controlled genetic crosses
-The ability to be reared in a laboratory environment
-The availability of numerous genetic variants
-An accumulated body of knowledge about their genetic systems
, ◉ Drosophila melanogaster Answer: Fruit fly
◉ C. elegans Answer: Nematode
◉ E. coli Answer: Example of model organism
◉ What are some of the implications of all organisms having similar
genetic systems? Answer: -that all life forms are genetically related
-that research findings on one organism's gene function can often be
applied to other organisms
-that genes from one organism can often exist and thrive in another
organism
◉ Sutton Answer: Genes are located on chromosomes
◉ Flemming Answer: chromosomes
◉ Centromere Answer: -attachment point for spindle microtubules
-hold sister chromatids together
◉ Metacentric Answer: centromere located in the middle
