Question

When a diploid female plant is crossed with teraploid male, the ploidy of the zygote will be? a) 4n b) 5n c) 2n d) 3n e) n

Answer 1

if a plant is diploid (2n), its gametes will be haploid (n); if it is tetraploid (4n), its gametes will be diploid (2n). The fusion of gametes from a male parent and a female parent (2n x n) produces a zygote (3n), which develops into a seed. The correct answer is d) 3n
