Insectsex is, for the most part, similar to other animal sex. For most insects, mating requires direct contact between a male and a female. Generally speaking, much like humans, the male of the insect species uses his sex organ to deposit sperm into the female's genital tract spurring on...
The author discusses research into the origins of gametes, focusing on the evolution of sexual reproduction through natural selection. Topics include the differentiation between eggs and sperm, the effect of gamete size on nutrition and efficiency in the ability to find a mate, and the parasitic ...
According to Carl Sagan in "The Dragons of Eden": Large organisms such as human beings average about one mutation per ten gametes [a gamete is a sex cell, either sperm or egg] -- that is, there is a 10 percent chance that any given sperm or egg cell produced will have a new and ...

jamesii to produce some unreduced 2x(2EBN) gametes. Due to the difference in EBN, the expected result of such a cross would be a triploid with two copies of the S. jamesii genome and one copy of the S. tuberosum genome. As far as I know, such crosses have been rarely reported ...
They communicate with each other by releasing hormones into the water, which is very similar to their style of reproduction: they expel their gametes — those are egg and sperm cells — out into the water column and just assume they'll find each other, just like they assume their friend ...
The team looked specifically at highly-conserved (i.e. unchanged via evolution) genes nanos and piwi, which are regulatory proteins involved in stem cell differentiation as well as gametogenesis—the process of creating germ cells and gametes (sperm and eggs). When the team mutated the nanos2 ...
How do you find the genotype of gametes? Does the mother or father determine the sex of the offspring? How did Mendel determine that both parents contribute genetic material to their offspring? Describe the validity of Punnett Squares in determining paternity for a child. ...
