A mallow is a little marshmallow organism that has 14 chromosomes (7 pairs).   It reproduces sexually.  Male mallows go through spermatogenesis to make sperm and female mallows go through oogenesis to make eggs.  The sperm and eggs each have 7 chromosomes due to meiosis.   When fertilization occurs, 7 chromosomes are given by each parent, and the baby mallow has 14 chromosomes. The mallow diploid (2n) number is 14 and the haploid (n) number is 7.

Baby Mallows: These babies are all siblings.  127 different offspring are possible due to the recombination of alleles.
