Tracing Genetic Variation from Prophase I Through Fertilization
Captions available
The idea
This capstone traces three independent sources of genetic variation, from one chromosome's internal shuffling through fertilization's combination of two parents' gametes.
Where people slip
These three mechanisms are cumulative, not redundant — removing any one narrows the range of possible offspring, since each contributes variation the other two do not.
