What would be the ploidy of the viable gametes produced by a tetraploid individual if nondisjunction of all chromosomes occurred in meiosis I?
a. Diploid
b. Tetraploid
c. Haploid
d. Triploidraploid individual and a diploid individual produces biologically fit offspring.

Respuesta :

A.  Diploid

During meiosis, the number of chromosomes is reduced by half.  Since a tetraploid cell has four copies of each chromosomes, gametes produced from that cell would be diploid, having only two copies of each chromosome.
