Why is tetrad analysis useful for studying genetics?

#Part-A Aptitude & General Biotechnology
  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.

Which of the meiotic pairing possibilities in tetraploids and their consequence is correct?

A-chromosomes pair as bivalents, segregate normally producing diploid gametes.

B- Chromosomes pair as quadrivalent, segregates normally producing tetraploid gametes.

C-Chromosome pair as Trivalents form, segregation leads to nonfunctional aneuploid gametes

 D- Chromosome pair as Trivalents form, segregation leads to producing diploid gametes
