why parthenogensis occur mostly in summer ?
Female. b/c parthenogenesis means development of animal without fertilization ........ and fertilization require sperm also therefore it only occur in female
Human parthenogenesis, the process of a human egg developing into an embryo without fertilization by sperm, has not been scientifically proven to occur naturally in humans. While it has been achieved in some animals, such as mice, it remains a topic of debate and research in the scientific community regarding its feasibility in humans.
Yes, parthenogenesis is a form of asexual reproduction where an egg develops into an embryo without fertilization by a male gamete.
Here are some examples of animals undergoing parthenogenesis: Reptiles Most reptiles reproduce sexually, but parthenogenesis has been observed in certain species of rock lizards, geckos, whiptails[1], and Komodo Dragons. Insects Honey bees, parasitic wasps, fire ants (Wasmannia auropunctata). Mammals In April 2004, scientists at Tokyo University of Agriculture used parthenogenesis to successfully create fatherless mice.
Most often in Arthropods, reproduction is by regular sexual reproduction i.e. by union of a sperm and egg. But variations of the usual process do occur. Aphids (class Insecta), for example, commonly reproduce by parthenogenesis, egg development without fertilization , and produce only females. But later in the summer, some of them convert to being males and then sexual reproduction occurs. Male honey bees are produced by an unfertilized egg. Both of the examples may still be called sexual reproduction since they involve development of the female gamete, that is, the egg. True asexual reproduction would not involve either gamete (sperm or egg) and all of the off spring would be genetically equal.
Tornadoes mostly occur in spring and early summer.
Tornadoes are more likely to occur in early summer.
In the US, tornado season begins in the Spring.
Tornadoes can occur at any time of day or year, but they mostly occur in spring and summer and in the late afternoon or early evening.
Humans are produced via sexual reproduction. That gives genetic diversity. You do not get such genetic diversity in case of the parthenogenesis. It is poor mode of reproduction.

Tornadoes are most common in the afternoon, though they are generally more frequent and more intense in the spring than in summer.
Most tornado occur in the spring or early summer, though it varies with the region. IN terms of time of day most tornadoes occur in the late afternoon.
Mostly in the summer and in all countries except Antarctica. Australia has the greatest chance of a wildfire
they most likely occur in Florida or the mostly occur in Texas
the summer Olympics occur every 4 years
They mostly occur when the tectonic plates in the earths systems rub against each other and they mostly occur in California.
