Why is tetrad analysis useful for studying genetics?

#Unit 8. Inheritance Biology

  1. Cells within a tetrad are haploid so genotype is directly reflected in the phenotype.

  2. Cells within a tetrad reflect the events of meiosis.

  3. Analysis of simple systems can elucidate general rules that apply more broadly.

  4. all of the above.
