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
