Here's some of the excerpts of the articles on male offspring from
parthenogenesis.

"Amazingly, these females can also give birth to male aphids without
having mated because they have an XO sex determining mechanism. Aphids
with two X chromosomes (XX) are females, and those with only one X
chromosome (XO, the O shows it's missing) are males. A special type of
meiosis occurs in the female to produce male offspring with only one X
chromosome, and this usually occurs late in the season. Mated females
will produce eggs that can better over-winter or survive dormant during
other harsh environmental conditions."

"In fact, another instance of parthenogenesis that produces only male
offspring was reported just over a year ago by David Chiszar at the
University of Colorado, Boulder, and Gordon Schuett of Arizona State
University West in Phoenix (This Week, 27 September 1997, p 23)-in a
virgin timber rattle snake. Since then, the researchers say they have
found evidence that other snakes may occasionally adopt the same type
of reproduction, as might the green iguana and-appropriately
enough-certain species of the Basilisk lizard, which is sometimes
called the "Jesus Christ lizard" for its ability to walk on water."

"One special form of asexual reproduction is parthenogenesis, in which
a new individual develops from an unfertilized egg. Dandelions and some
other plants practise parthenogenesis, and it also occurs in animals
such as aphids, some fish, some lizards, and even in some birds,
including some domestic turkeys. Again, the parthenogenetic offspring
and the parents collectively form a clone. But it is possible to
reproduce parthenogentically without producing a clone. Thus the male
offspring of bees (the drones) develop from unfertilized eggs but their
genes are recombined in the process so they are not genetically
identical to each other or to the queen (who, of course, is female
rather than male). But this is a special case; typically the products
of parthenogenesis form a clone."
