Question

Hypothesize one way that a diploid organism could have offspring that are 3n or 4n

Answer 1

Popypoidy mainly occurs in the plants when there is total non-disjunction of sister chromatids occurs during the meiosis of gametic cells. So as before the meiosis the number of chromosomes doubles and after meiosis every cell get half the number of chromosome so after segregation failure autopolyploidy occurs in plants.

Triploid condition can also be seen in animals when two sperms fertilize one ovum. So, in this case, the chromosome number reaches to 69(23+23+23) which means chromosome number become 3n.

Answer 2

Diploid refers to a cell that has two copies of each chromosome. One way that a diploid organism could have an offspring that are 3n (triploid) or 4n is when the chromosomes don't separate during meiosis.

Triploid refers to some cell that have 3 copies of each chromosomes for a total of 69 chromosomes.
