As I read in biology and genetic texts, a grain of pollen carries one copy
of one-half of the parent's genetic material. The egg in the ovary carries
the
other half, and when the two unite, you get an embryo (seed). The analogous
structures in the animal kingdom are sprem and ovum, and, at least in
mammals,
the first sperm to the egg wins. I would imagine the limiting factors in the
pod would
be a) the amount of eggs present b)who got there first c) the compatibility
of the
pollen and egg and d)some things I am probably missing. My education was
chemistry
and physics with just a bit of biology. Where is Bill Shear when we need a
good answer? :)
