When twins are the result of two eggs being fertilized at the same time (non identical twins) there is some evidence to show that there is a genetic basis for this kind of twins. However, it is only their mother that has any effect on the chances of having non identical twins; there is no known mechanism for a father to cause the release of more than one ovum
When twins are the result of the zygote splitting into two embryos (identical twins) then this is considered a random act nobody is responsible.

Why female anopheles mosquito is responsible to transfer plasmodium in humanbeing and why not in the male?
Male (and female) mosquitoes feed on flowers. However, it is only the female mosquito which bites humans. "She" does this in order to obtain proteins from the blood plasma, which she needs for her eggs. (The male mosquito does not need these proteins, hence it does not bite the human.) Since the female mosquito is the only one being exposed to human blood, it is the only one which will transmit its contents, including malaria. :)
Does the mother or the father determine the sex of the offspring?
No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female. The sperm have either an x chromosone or a y chromosone which carries the male sex determination. It is by chance and timing which one fertilized the egg first. If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. No, it is the male. The female eggs or ovum only have the x chromosone which develop into a female.

If it is a x chrromosone then the offspring is a female. If the y chromosone fertilized the egg, then chemical changes occur resulting in a male fetus. It is found in both male and female chromosomes.....found in answer key
